Here, we report a fabrication method of optoelectrical probes for precise modulation of neurons. A linear array of flip-chipped green resonant-cavity μLEDs (RCLED) with an emitting aperture of 50 μm is integrated on Si platform as the stimulation source. Due to the top/bottom Bragg reflectors, the RCLEDs' output light view-angle is narrowed to &lt;90°. The emission wavelength demonstrates remarkable stability under various injection current densities. Under the 50 A/cm2 driving current density, the RCLEDs' output optical density is 100 mW/mm2 and maximum temperature rise is 0.5 °C, both of which exhibit great improvement compared with those of the optical probes on sapphire substrate. Using these green RCLED probes to stimulate Mac-mCherry photosensitive protein, the analgesia and inhibition effects for medium prefrontal cortex GABAergic neurons are verified. This work provides an effective approach to fabricate integrated microscale light sources for precise stimulation and modulation of neurons, which facilitate the study of complex neural functions.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"17 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143569762","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional means of reliability studies include, but are not limited to, x-ray diffraction, atomic force microscopy, Raman spectroscopy, and electron microscopy et al. However, most of these methods are ex situ studies after material or device failure and thus have some limitations. In situ transmission electron microscope (TEM) is a favorable technology to observe the degradation and failure process of materials and devices in real time, which may provide effective guidance in material growth, device structure design, device process optimization, and reliability improvement. In recent years, in situ TEM technology has been gradually used by researchers to study WBS materials and devices. In this review, we present a comprehensive and systematic review of in situ TEM works on diamond, Ga2O3, GaN, and SiC materials and devices, with a particular focus on the progress of the technology in the reliability study of such materials and devices.

As a result, a wide variety of PDs on planar substrates have been reported using various light sensitive materials and traditional micro-/nano-fabrication technologies. In recent years, considerable efforts have been devoted to developing PDs with flexible form factors and using eco-friendly materials and approaches. These efforts have resulted in exploration of degradable materials and printed electronics as a resource-efficient route for manufacturing and to contain end-of-life issues. This paper reviews such new advances, particularly focusing on flexible PDs based on inorganic (e.g., crystalline silicon, compound semiconductors, metal oxides, etc.) semiconductor nanostructures [e.g., Nanowires (NWs), Nanoribbons (NRs), etc.]. The advantages and disadvantages of various bottom-up and top-down methods explored to realize the nanostructures and the wet (solution-processable) and dry printing and assembly methods to print the nanostructures on flexible substrates, are discussed along with their suitability for various applications. This discussion is supported by a comparative analysis of printed PDs in terms of key performance metrics such as responsivity, detectivity, ILight/IDark ratio, response speed, and external quantum efficiency. This comprehensive discussion is expected to benefit researchers and practitioners from academia and industry interested in the field of printed and flexible PDs.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"211 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143546501","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, understanding lattice dynamics is crucial for regulating thermal conduction, as the intrinsic limit mainly depends on phonon dispersions. Conventionally, thermal conduction is regulated through heat-carrying acoustic phonon manipulation due to their high group velocities, which are widely utilized in materials such as thermal coatings and thermoelectrics. In recent years, with advancements in thermal transport, optical phonons have been of great interest for tuning thermal conduction, with a particular focus on those with special dispersive behaviors; however, the microscopic mechanisms are significantly different. This review aims to provide a comprehensive understanding of the effect of optical phonons, especially those with high weights on thermal conduction in advanced materials, as well as discuss the fundamental mechanisms, including (i) phonon bandwidth, (ii) phonon gap, (iii) avoided-crossing, (iv) phonon nesting/twinning, (v) optical-acoustic phonon bunching, and (vi) multiple optical phonons.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"85 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539106","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To accommodate these applications, suitable methods for generating the quantum states are needed. Today, the quantum states are often produced by a spontaneous nonlinear process in a standard nonlinear material, followed by a series of optical elements necessary for encoding the desired state on the generated photons. In this review, we consider an alternative approach of structuring the nonlinearity of the crystal so that the desired quantum state will be generated directly at the crystal, without the need for additional elements. Our main focus here is on bulk crystals having structured second-order nonlinearity. The rising interest in these nonlinear metamaterials is fueled by advancements in the ability to efficiently simulate and design spontaneous parametric downconversion (SPDC) processes, as well as by new capabilities of structuring the nonlinearity of ferroelectric crystals, either by electric field poling or by laser-induced writing. As a result, nonlinear metamaterials were recently used to directly shape the spatial and spectral correlations of quantum light that is generated in SPDC. The paper covers the theoretical background and the design and fabrication methods of bulk nonlinear metamaterials for generating quantum light, as well as a series of demonstrations of the use of metamaterials in quantum optical applications.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"17 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143539113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During this time, researchers have shown extraordinary demonstrations of nonlinear processes such as unity order index change via intensity dependent refractive index, enhanced second harmonic generation, saturable absorption in ultra-thin films and more recently, frequency shifting via time modulation of permittivity. More recently, remarkable strides have also been made in uncovering the intricacies of ENZ materials' nonlinear optical behavior. This review provides a comprehensive overview of the various types of nonlinearities commonly observed in these systems, with a focus on Drude based homogenous materials. By categorizing the enhancement into intrinsic and extrinsic factors, it provides a framework to compare the nonlinearity of ENZ media with other nonlinear media. The review emphasizes that while ENZ materials may not significantly surpass the nonlinear capabilities of traditional materials, either in terms of fast or slow nonlinearity, they do offer distinct advantages. These advantages encompass an optimal response time, inherent enhancement of slow light effects, and a broadband characteristic, all encapsulated in a thin film that can be purchased off-the shelf. The review further builds upon this framework and not only identifies key properties of transparent conducting oxides that have so far made them ideal test beds for ENZ nonlinearities, but also brings to light alternate material systems, such as perovskite oxides, that could potentially outperform them. We conclude by reviewing the upcoming concepts of time varying physics with ENZ media and outline key points the research community is working toward.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"1 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143517932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intensive studies have been conducted about the phonon mechanism of isoelectronic alloying since the 1950s. Very recently, the specific role of aliovalent doping was elucidated in the half-Heusler NbFeSb system. Here, we have theoretically and experimentally investigated the mechanism of reducing thermal conductivity through aliovalent doping by combining first-principles calculations and neutron diffraction studies for the case study of the TiCoSb half-Heusler system. The softening of the acoustic branches induced by aliovalent doping can effectively reduce the phonon group velocities. Moreover, the introduction of compensating defects, resulting from changes in the Fermi level, plays a vital role in decreasing the relaxation time of phonons, as demonstrated by the analysis of neutron powder diffraction. Due to these two factors, doping with adjacent elements results in a significant reduction in lattice thermal conductivity (for instance, Ni doping at the Co site in the TiCoSb half-Heusler system), especially in the low-temperature range. Our findings provide valuable insight into the phonon scattering mechanism in aliovalent-doped materials and demonstrate the role of compensating defects in heat transport, which is applicable to other doped semiconductor systems.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"22 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143506870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating x-ray-guided wireless manipulation with UMRs, we aim to address challenges associated with precise and controlled blood clot intervention. The untethered nature and size of these robots enhance maneuverability and accessibility within complex vascular networks, potentially improving clot removal efficiency. We explore mechanical fragmentation, chemical lysis, and hybrid dissolution techniques that combine mechanical fragmentation with chemical lysis, highlighting their potential for targeted and efficient blood clot removal. Through experimental validation using an ex vivo endovascular thrombosis model within the iliac artery of a sheep, we demonstrate direct revascularization of a 13-mm-long, 1-day-old blood clot positioned inside the left common iliac artery. This was achieved by deploying a UMR into the abdominal aorta within 15 min. Additionally, both mechanical fragmentation and hybrid dissolution achieve a greater volume rate of change compared to no intervention (control) and chemical lysis alone. Mechanical fragmentation exhibits clot removal with a median of 0.87 mm3/min and a range of 2.81 mm3/min, while the hybrid approach demonstrates slower but more consistent clot removal, with a median of 0.45 mm3/min and a range of 0.23 mm3/min.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"26 2 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
