Specifically, the non-volatile ferroelectric polarization and bulk photovoltaic effect (BPVE) make them ideal candidates for self-powered photodetection. Photodetectors based on BPVE with a large ferroelectric polarization are highly desirable, due to the combination of high photo-response efficiency and ultrafast response. In this work, the thickness-dependent sliding ferroelectric BPVE and its ultrafast carrier dynamics in 3R-MoS2 layers are investigated. The sliding ferroelectricity and its associated switchable BPVE response are confirmed at room temperature. With an approximate twofold increase in thickness, a near sevenfold enhancement in short-circuit current, and a tenfold rise in open-circuit voltage are observed, demonstrating an enhanced BPVE. More importantly, due to the enlarged polarization in thicker 3R-MoS2, time-resolved photocurrent (TRPC) measurements reveal that the log-log slope of the response time versus thickness is less than 2, breaking through the conventional L2 (thickness)-dependent limit of the drift-diffusion model, thereby enabling ultrafast response even in thick layers. This work provides a new pathway to high-performance ultrafast bulk photovoltaic photodetectors.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500101","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One effective strategy involves tuning mechanical strain, which can be induced through lattice mismatch, electric fields, or applied mechanical force. Recent advances in fabricating freestanding single-crystalline complex oxide membranes have opened new opportunities for integrating these materials onto previously incompatible platforms such as metals and flexible polymers for next-generation device applications. A key step in strain engineering is understanding and controlling the integration of such materials with flexible substrates. In this study, the integration and adhesion of freestanding single-crystalline La0.7Sr0.3MnO3 (LSMO(001)) membranes onto metallic surfaces (Au, Pt, and TiN) coated on flexible polymer substrates is demonstrated. It is found that the choice of metal underlayer significantly influences the ability to strain the membrane. Using TiN-coated polymer support, a uniform strain of ≈1% in LSMO membranes, along with strong adhesion between the membrane and substrate, is achieved. Theoretical calculations reveal that strong Ti─O bonding and compact in-plane lattice matching at the LSMO(001)/TiN(111) interface lower the interface formation energy compared to noble metals. These findings offer valuable insights for selecting suitable platforms to apply external mechanical stress to freestanding oxide membranes, facilitating their integration into flexible electronic systems.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500075","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145242938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among several combinations of materials that have shown intriguing behaviors, spinterfaces based on antiferromagnetic materials received much less consideration, despite the dramatic increase in attention recently drawn by the antiferromagnetic declination of spintronics. In this work, an antiferromagnetic spinterface based on the transition metal oxide NiO, a widely studied antiferromagnetic insulator with one of the highest critical temperatures, has been realized and characterized. As for the molecular counterpart, Co tetraphenyl porphyrin (CoTPP) is a very promising choice, being sublimable in vacuum and paramagnetic. CoTPP/NiO(001) spinterfaces are experimentally investigated with respect to their morphology, structure, electronic, and magnetic properties. Theoretical calculations have also been performed to circumstantiate and support the measurements. Although characterized by a relatively weak interface coupling, spin-dependent hybridization is observed at the interface, which makes the CoTPP/NiO a perfect system for initiating the exploration of a molecular antiferromagnetic spintronics.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500076","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145243149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a radar stealth context, it often translates to the reduction of the radar cross-section (RCS). However, other routes that take advantage of radar signal processing exist. For instance, a solution has recently been developed, which consists in compensating the motion-induced Doppler shift with a time-modulated metasurface since Doppler radars filter out static targets to avoid being swamped by radar clutter (buildings, trees, etc.). Such a coating, referred to as a Doppler cloak, is able to compensate any frequency shift. However, frequency-modulated radar signals require a broadening of the frequency conversion bandwidth of existing Doppler cloaks, which are all designed for harmonic signals. In this work, the focus is thus placed on a broadband Doppler cloak able to suppress the Doppler information over a wide frequency range. To achieve this, the reflection coefficient of a varactor diode-loaded metasurface is linearized in time to obtain a linear phase ramp necessary to shift the frequency of impinging waves. Numerical and experimental validations are performed using frequency-modulated continuous wave (FMCW) broadband radar signals over the VHF-UHF range.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145243041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mathematical expressions are derived for key properties such as the superconducting (SC) order parameters, the SC transition temperature, the density of states (DOS), and condensation energy. Utilizing these expressions, Matplotlib in Python is employed to generate phase diagrams illustrating the SC order parameters versus temperature, the SC transition temperature versus SC coupling paramete, the DOS versus excitation energy, and the condensation energy versus the SC transition temperature, temperature, and inter-band pairing potential. These phase diagrams reveal key findings. First, both the SC order parameters and the condensation energy exhibit a decreasing trend as the temperature increases and vanish completely at the SC critical temperature. Second, the DOS initially increases with increasing excitation energy, until it reaches zero temperature SC order parameter (Δ(0)), which corresponds to the energy gap at zero temperature. Beyond this point, the DOS starts to decrease. Finally, the phase diagrams illustrate that the SC transition temperature increases as each intra-inter-band pairing potential increases.","PeriodicalId":100035,"journal":{"name":"Advanced Physics Research","volume":"4 10","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/apxr.202500054","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145243124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
