Terahertz (THz) science and technology is the latest field to witness phenomenal growth in 6G communication and quantum materials devices. Such advancements depend on the ability to control both the amplitude and phase-shift of THz radiation, with the latter being particularly crucial. Currently, free-space THz phase shifters exploit the intrinsic changes in carrier density, resulting in a weak response that can be amplified by metamaterial structures, but at the expense of a significantly reduced bandwidth. In this work, we demonstrate a novel mechanism that leverages only the intrinsic property of magnetoelastic coupling to induce a giant THz phase modulation. An unprecedentedly large phase-shift of 3.35π radians at ∼0.9 THz occurs during the magnetoelastic phase transition between 72 and 35 K in Ba3BiIr2O9. This is accompanied by a remarkable figure-of-merit that is four to five times greater and spans a significantly broader spectral range than that of other above π/2 free-space modulators. Corroborated by theoretical calculations, we show that the spin–phonon coupling dynamics have a defining influence in altering the dielectric function that underlies these properties. These findings present the prospect of integrating magnetoelastic quantum materials in emergent THz communication tools, which rely on phase-shift modulation for information processing.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"5 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144165227","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}

Using rigorous first-principles calculations, we identify tetragonal tantalum nitride (t-TaN) as a narrow bandgap semiconductor that uniquely achieves both high thermal conductivity (κ) and high carrier mobility (μ). At room temperature, t-TaN demonstrates an extraordinary κ of up to 677 W m−1 K−1, surpassing that of most widely used semiconductors. This remarkable κ arises from the synergistic effects of phonon bunching and a substantial frequency gap in the phonon spectrum, which significantly suppresses phonon–phonon scattering. Even more strikingly, t-TaN exhibits exceptional hole μ exceeding 4700 cm2 V−1 s−1 at room temperature, outperforming all known high-κ bulk semiconductors. This ultrahigh μ is attributed to its elevated Fermi velocity and weak electron–phonon coupling, stemming from its unique electronic and phononic structures. These findings position t-TaN as a compelling candidate for advanced electronic and optoelectronic applications, while also offering a transformative perspective for discovering high-performance semiconductors with dual advantages.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"151 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154194","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}

Therefore, the development of adaptive bionic vision systems with high efficiency, low complexity, and minimal energy consumption has become a key objective. However, most adaptive devices suffer from either complex structures or non-reconfigurable functionalities, hindering the further application for bionic vision systems. Here, for the first time, an asymmetry-Schottky-barrier MoS2 phototransistor is demonstrated for reconfigurable visual system with visual selective memory and graded adaptation functions. More importantly, the device exhibits a new record with the ultra-low energy consumption of ∼90 zJ per synaptic event. Several important adaptive behaviors, such as the sensitivity, desensitization, accuracy, and self-recovery, are successfully realized and adjusted by asymmetry-Schottky-barriers.

In this study, we try to apply a similar strategy to reduce the barrier of sliding ferroelectricity in van der Waals bilayers/multilayers with commensurate interfaces, since the writing speed in ferroelectric memories would be enhanced almost exponentially upon such reduction. A major challenge is that incommensurate interfaces are generally non-ferroelectric, and our solution is asymmetric across-layer stacking. We propose a type of superlubric sliding ferroelectricity in homobilayers separated by a hetero-layer, where the polarizations stem from symmetry breaking in across-layer commensurate stacking configurations. Meanwhile, the incommensurate interfaces of adjacent layers lead to unprecedented low switching barriers. For example, the switching barrier of 3R bilayer MoS2 will be, respectively, reduced by around two or one order of magnitudes (0.027 and 0.167 meV/atom) if they are separated by a graphene or BN monolayer, and the required voltage for switching can be about one order of magnitude lower. Such superlubric sliding ferroelectricity widely exists in various similar sandwich trilayer systems, where symmetry breaking induced by across-layer stacking configurations may also lead to considerable polarizations. With switching barriers three–four orders of magnitude lower compared with prevalent ferroelectrics, epochal applications, such as superlubric nanogenerators and picosecond ferroelectricity, may become feasible.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"10 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144130374","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 this review, we introduce the recent trends in various CRISPR delivery systems. First, we explain the impact of CRISPR in clinical settings and its history. We then focused on the physics of gene delivery systems, particularly regarding the migration of nanoparticles (NPs) under flow, cellular uptake, and formulation using microfluidics. Subsequently, various CRISPR delivery systems, both viral and non-viral, and their applications in disease therapy were introduced. Viral carriers include lentiviruses, adeno-associated viruses, and viral capsids. Exosomes, silica NPs, polymeric NPs, and lipid NPs are representative non-viral gene delivery carriers.

However, the majority of existing broadband photodetectors are limited in their detection range by the material bandgap, making it difficult to achieve detection from ultraviolet to infrared wavelength, and the response performance is not uniform for each waveband. Additionally, a significant disparity persists between self-powered photodetectors and conventional semiconductor photodetectors with regard to pivotal photodetection parameters, such as responsivity. To address these problems, a broadband self-powered photodetector based on two-dimensional WSe2/three-dimensional 4H-SiC heterojunction is proposed. The wide bandgap of 4H-SiC and the narrow bandgap of WSe2, in conjunction with the built-in electric field of the heterojunction and the metal/semiconductor interface, enable the device to detect light from 200 to 1100 nm and achieve a uniform high-performance response to the ultraviolet, visible, and infrared wavelengths simultaneously. Under 275 nm illumination (Vds = −1 V), the device demonstrates a responsivity and detectivity of 25.7 A/W and 3.85 × 1012 Jones, respectively, and exhibits an ultra-fast rise/decay time of 42/42 μs under 635 nm illumination (Vds = −1 V). Moreover, under Vds = 0 V and 635 nm illumination, the responsivity and detectivity of the device are 1.22 A/W and 2.67 × 1011 Jones, respectively. The device exhibits great capability in high-performance, broadband, self-powered light detection, providing a new direction for the development of next-generation energy-saving, high-sensitivity optoelectronic integration technology.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"44 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144122404","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}

This approach has proven effective in imparting ferromagnetic semiconductor characteristics, which are essential for applications in spin light-emitting devices and semiconductor spintronics. Here, we synthesized Cs4PbBr6 and Mn-doped Cs4PbBr6 (Mn:Cs4PbBr6) perovskite single crystals. Magnetization measurements reveal that Mn:Cs4PbBr6 exhibits a ferromagnetic behavior at 30 K. Complementary density functional theory calculations suggest that the observed magnetism arises from the introduction of single-spin energy states by the doped Mn in the bandgap. Moreover, we observed a negative photoconductivity (NPC) effect at room temperature in the Mn-doped samples. This NPC phenomenon is attributed to the absorption and desorption of oxygen molecules on the surface of Mn:Cs4PbBr6 crystals.
