Due to its larger bandgap and higher optical damage threshold, LT can be employed for efficient nonlinear optical frequency conversion in the ultraviolet (UV) wavelength range. Here, we report on fabrication of monolithic, high-quality LT metasurfaces, composed of periodic arrays of LT truncated square pyramids, created by partially etching of a LT thin film layer using a focused ion beam milling process. These pyramidal structures introduce discrete translational symmetry, which allows for the folding of guided-mode dispersion into the first Brillouin zone, leading to the formation of guided mode resonances with Q-factors that can be easily controlled by the height of LT pyramids. The measurements show a Q-factor up to approximately 640 at 786 nm. By leveraging the strong field localization of these high-Q resonances, we demonstrate enhanced second-harmonic generation at 393 nm with an absolute conversion efficiency of 0.042%, establishing a new benchmark for the UV harmonic generation in dielectric metasurfaces. Moreover, our fabrication technique can be readily adapted to a wide range of other material platforms, opening new avenues for the development of high-quality UV metasurfaces and advanced nonlinear photonic meta-devices.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"51 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144577861","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}

Unlike electrostrictive and magnetostrictive effects, it does not involve complex circuits, therefore offering a promising prospect of accomplishing the advanced, compact, and remote-control devices. The key step to produce the light-induced strain of practical value is to design highly efficient photostrictive materials. Based upon the nature of the material systems to be explored for micro-optomechanical devices, the photostriction in inorganic–materials-based systems, including semiconductors, transition metal oxides, halide perovskites, and ferroelectrics in bulk and two-dimensions, are summarized herein. For each material, the feasible strategies of compositional engineering, processing conditions, and sample sculpturing, with a special focus on the meticulous tailoring of multiple phase boundaries in representative ferroelectric systems to produce significant photostriction, are given. Since ferroelectric photostriction is accounted as the superposition effect of photovoltaic and inverse piezoelectric effects, both effects are introduced and discussed. Finally, perspectives on future research of photostrictive materials are added. We believe that this review will bring new insights in producing highly efficient photostrictive materials for the commercial production of upcoming state-of-the-art micro optomechanical devices.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"8 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144577871","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}

It covers classical and modified theoretical equations and explores strategies for modifying acoustic environments through resonant coupling in bubbles. Techniques, such as applying external forces, introducing surfactants, and creating micropatterned designs for structuring bubbles, are discussed. This review evaluates the superior acoustic properties of underwater bubble metamaterials, including their reflection, absorption, and transmission capabilities and their potential applications in marine environments.

Additionally, the larger polarization and band offset barriers between high indium content InGaN quantum wells and GaN quantum barriers increase the forward voltage. In blue and green LEDs, random alloy fluctuations and V-defects play a key role in reducing the forward voltage. When V-defects are present, either naturally or intentionally introduced, they create an alternative path for carrier injection into the MQWs through the V-defect sidewalls. This injection mechanism explains the turn-on voltages of green LEDs. However, in InGaN red LEDs, these two phenomena do not reduce the forward voltage as effectively as in blue and green LEDs, and consequently, the computed forward voltage remains significantly higher than the measured one. Furthermore, currents are observed at low voltages before the turn-on voltage (V&lt;ℏω/e=2.0 V) of red LEDs. To address this, we introduce dislocation-induced tail states in the modeling, suggesting that leakage current through these states may play a significant role both below and at turn-on voltages. The simulation also indicates that leakage carriers below turn-on accumulate, partially diffuse in the QWs, screen the polarization-induced barrier in the low injection regime, and further reduce the forward voltage. Despite these beneficial effects, a drawback of dislocation-induced tail states is the enhanced nonradiative recombination in the dislocation line region. This study provides a detailed analysis of device injection physics in InGaN QW red LEDs and outlines potential optimization strategies.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"27 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144533221","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}

While the relationship between CDWs and superconductivity has been extensively studied, the interplay between CDWs and magnetic order remains largely elusive. Kagome lattices, with their intrinsic nontrivial topology, charge order, and magnetism, provide a compelling framework for investigating these interactions. In this work, we unravel the orbital origins of magnetic moment modulation induced by CDW in the kagome magnet FeGe, a system exhibiting a unique coupling between CDW and magnetism. The combination of x-ray absorption spectroscopic experiments and first-principles calculations shed light on the temperature-dependent behavior of Fe3d–Ge4p orbital hybridization and corroborate its significant impact on the magnetic properties of FeGe.

While acoustic patterning has demonstrated remarkable control over microscale spatial configurations, its scalability into three-dimensional (3D) fabrication has remained constrained by challenges in bonding limitations and vertical stacking. To solve this challenge, hybrid acoustic-assisted 3D printing integrates acoustophoresis with established methods, such as direct ink writing and stereolithography, enhancing material deposition accuracy, microstructure alignment, and porous structuring of 3D printed products. However, these hybrid systems remain tethered to layer-by-layer architectures, limiting the full potential of acoustic techniques. Recent breakthroughs in standalone acoustic 3D fabrication, leveraging levitation, focusing, and ejection, have unlocked potential in contactless, layerless, and flexible multi-material assembly. Acoustic levitation systems enable mid-air construction on non-planar surfaces, and focused ultrasound techniques facilitate deep-penetration polymerization and acoustic droplet ejection advances nozzle-free droplet-based bioprinting.
