Apart from overcoming issues of fluidic damping and electrical interfaces, there is a great challenge of bringing microanalytes to these devices with the required precision and scaling for high throughput sensing. Herein, we address the above challenges by proposing a self-excited localized acoustic manipulation methodology based on a piezoelectric micromechanical diaphragm resonator (PMDR). Such a PMDR integrates acoustofluidics and mass sensing functions in tandem on a single device. Particle enrichment is realized within tens of seconds and the limit of detection is enhanced by mitigating common issues such as low capture rate and non-uniform distribution. The developed PMDR is versatile in its applicability to a range of particle sizes and densities for both acoustofluidic actuation and in situ mass sensing. This work addresses long-term technical challenges of inaccurate and inefficient measurement of liquid phase resonance mass sensing with great application potentials in biochemical detection and environmental monitoring.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"2 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142924652","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}

In recent years, there has been a surge in research on polarization-sensitive photodetectors that utilize anisotropic two-dimensional (2D) materials. The essence of these 2D polarization-sensitive photodetectors is rooted in the anisotropic characteristics that arise from the asymmetric crystal lattice of the 2D materials in question. This anisotropy is manifested in both optical and electrical behaviors due to the asymmetrical nature of the crystal structure. This article systematically categorizes anisotropic 2D materials and offers an insightful overview of their crystal structures. It also introduces various optical and electrical characterization techniques designed to elucidate the anisotropic properties of these materials. The focus of the article then shifts to detailing the current state of research in the realm of anisotropic 2D material-based polarization-sensitive photodetectors. It provides a comprehensive description of the working principles behind polarization-sensitive photodetectors with different structural designs, shedding light on the underlying mechanisms that enable their polarization sensitivity. In conclusion, the article summarizes the findings of this review, highlighting the advancements and challenges in the field.

One of the most exciting approaches to modulate materials performance is mobile ion/vacancy insertion for inducing changes in relevant electrical, optical, or magnetic properties, among others. Unveiling the interplay between changes in the concentration of mobile defects (like oxygen vacancies) and functional properties in relevant materials represents a step forward for underpinning the emerging oxide iontronics discipline. In this work, electrochemical oxide-ion solid-state pumping cells were fabricated for analog control of the oxygen stoichiometry in thin films of mixed ionic-electronic conductor La0.5Sr0.5FeO3-δ. We demonstrate over more than four orders of magnitude electronic conductivity control at 50 °C within the same crystallographic phase through precise and continuous voltage control of the oxygen stoichiometry. We show that behind the modification of the transport properties of the material lays a paramagnetic-to-antiferromagnetic transition.

However, for practical applications, it is crucial to effectively filter out the driving beam from the high harmonics. In this study, we leverage the distinctive properties of a Bessel–Gauss (BG) beam to introduce a novel approach for spatial filtering, specifically targeting soft x-ray harmonics, releasing with a high-photon flux simultaneously. Our simulations reveal that by finely adjusting the focus geometry and gas pressure, the BG beam naturally adopts an annular shape, emitting high harmonics with minimal divergence in the far field. To achieve complete spatial separation of the driving beam and harmonic emissions, we pinpoint the optimal gas pressure and focusing geometry, particularly under overdriven laser intensities, for achieving good phase matching of harmonic emissions from short-trajectory electrons within the gas medium when the exact ionization level is higher than the “critical” value. Additionally, we establish scaling relations for sustaining optimal phase-matching conditions crucial for spatially separating the driving laser and the high-harmonic field, especially as the wavelength of the driving laser increases. Furthermore, our analysis demonstrates a substantial enhancement of harmonic yields by at least one order of magnitude compared to a truncated Gaussian annular beam. We also show that under accessible experimental conditions, soft x-ray photon flux up to 1010 photons/s at 250 eV can be achieved. The utilization of the BG beam opens up a promising pathway for the development of high-flux attosecond soft x-ray light sources, poised to serve a wide range of applications.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"13 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142848914","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}

The SkHE usually results in annihilation of skyrmions due to the destructive skyrmion–boundary interactions. In this review, we provide a comprehensive overview of the fundamentals of the SkHE as well as the recent advances in manipulation and suppression of the SkHE in various types of magnetic materials. Additionally, we introduce some SkHE-free topological spin textures, such as skyrmioniums and hopfions. This review covers the following aspects: origin of the SkHE and its implications on spintronics, manipulation of the SkHE by external magnetic fields and geometrical engineering, and properties of SkHE-free spin textures.

With a substantial number and types of sensors over a large area, the low-cost fabrication is desirable for e-skin. In this regard, printing electronics attract the attention as it allow efficient use of materials, “maskless” fabrication, and low-temperature deposition. Additionally, the use of e-skin in real-time applications calls for faster computation and communication. However, due to limitations of widely used materials (e.g., low mobility) and the printing tools (e.g., poor print resolution), the use of printed electronics has been restricted to passive devices for low-end applications until recent years. Such limitations are now being addressed through high-mobility materials and highlighted in this review article, using e-skin as a vehicle. This paper discusses techniques that allow printing of high-quality electronic layers using inorganic nanostructures, and their further processing to obtain sensors, energy harvesters, and transistors. Specifically, the contact printing, transfer printing, and direct roll printing are discussed along with working mechanisms and the influence of print dynamics. For the sake of completeness, a few examples of organic semiconductor-based devices are also included. E-skin presents a good case for 3D integration of flexible electronics, and therefore, the use of high-resolution printing to connect various devices on a substrate or 3D stack is also discussed. Finally, major challenges hindering the scalability of printing methods and their commercial uptake are discussed along with potential solutions.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"12 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142820837","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}
