However, achieving efficient luminescence under blue light excitation remains a significant challenge. Herein, we present a novel zero-dimensional hybrid copper iodide [Li(H2O)(Benzo-15-crown-5)2]2Cu4I6 (abbreviated as [LB]2Cu4I6), as a highly efficient and blue-light-excitable emitter with potential in lighting and x-ray imaging applications. This compound exhibits an ultrabroad excitation band spanning from 250 to 500 nm, upon blue light, ultraviolet, or x-ray excitation, delivers strong broadband yellow emission centered at 541 nm with a high photoluminescence quantum yield (PLQY) of 92.1%. Benefiting from their strong photoexcitation under blue light, high PLQY, and good environmental stability, a high-performance white light-emitting diode was developed, achieving a commercial-level luminous efficiency of 101.6 lm W−1, a high color rendering index of 87, and a record half-lifetime of 2352 h. Additionally, [LB]2Cu4I6 demonstrates outstanding x-ray scintillation properties with a high light yield of 83 904 photons MeV−1, a low detection limit of 72.3 nGy s−1, and a competitive spatial resolution of 10.3 lp mm−1 for x-ray imaging.

While traditional far-field spectroscopy and electromagnetic simulations have been used to study Mie scattering, these methods lack real-space imaging capabilities, limiting their ability to capture single-particle scattering phenomena. Scanning probe microscopy-based nanoscopy techniques have become essential for studying Mie scattering at the nanoscale to address this limitation. This review explores the theoretical foundations of Mie scattering and the role of near-field microscopy in bridging the gap between theory and experiment through high-resolution imaging. By focusing on real-space imaging, we highlight the practical aspects of Mie scattering and its applications in fields such as biosensing, photocatalysis, and materials science. Nanoscopy techniques allow for direct visualization of scattering processes in nanostructures, offering more profound insights into how NPs interact with light at the nanoscale. Additionally, we discuss the potential of artificial intelligence (AI) to enhance near-field analysis, providing more accurate interpretations of Mie scattering phenomena. In conclusion, combining advanced nanoscopy and AI-driven analysis will significantly advance our understanding of Mie scattering and its diverse applications in various scientific and technological fields. The synergy between cutting-edge imaging methods and computational simulation not only enriches our theoretical understanding of scattering phenomena but also accelerates the development of next-generation photonic devices, paving the way for a wide range of practical applications across scientific and technological domains.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"163 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144899797","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}

Combining a high-pressure apparatus with a low-temperature cryostat requires the design of a compact-scale high-pressure apparatus which generally results in reduced sample volume. In the magnetic measurements, this requires the use of a superconducting quantum interference device (SQUID), which is a highly sensitive magnetic device for detecting changes in minute magnetic fluxes. In this review, two types of SQUID magnetometers for pressure (P) of up to 30 GPa are reviewed. One is a commercial SQUID magnetometer with a miniature diamond anvil cell (DAC) covering a wide temperature range of 1.8–400 K, and the other is a vibrating-coil SQUID magnetometer equipped with DAC, which provides more accurate measurements. The former was used for oxygen molecules, molecule-based magnets, permanent magnets, organic radial ferromagnets, and lanthanide ferromagnets, whereas the latter was applied to organic radial ferromagnets, samarium (Sm), and an iron-based superconductor. Further developments of accurate magnetization measurements at high pressures are important for condensed matter studies on magnets and superconductors.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"55 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701723","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 coupled electron–phonon transport, we discuss the basics of electron–phonon interactions and their effects on phonon dynamics, thermalization, and nonequilibrium thermal transport. For the phonon–spin interaction, nonequilibrium transport formulation is introduced first, followed by the physics of spin thermoelectric effect and strategies to manipulate them.

While manipulation techniques such as strain (via substrates), electric fields, and temperature are commonly employed, switching induced by charged defects between different polar topological structures remains a rarely observed phenomenon. In this study, we demonstrate that oxygen vacancies can effectively enable the switching between flux-closure and center-type topological structures in PbTiO3 (PTO) nano-island arrays. Supported by evidence from x-ray photoelectron spectroscopy, scanning Kelvin probe microscopy, and piezoresponse force microscopy, we demonstrate that a high concentration of oxygen vacancies favors the formation of center-type domains, while the topological structure transitions to the flux-closure configuration following elimination of oxygen vacancies via in situ annealing under various gas atmospheres. This deterministic switching between the two polar topological structures highlights the critical role of charged defects and opens new avenues for the manipulation of polar topological structures in future applications.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"107 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144603868","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}

However, traditional structures—such as planar heterojunctions (PHJs) and bulk heterojunctions (BHJs)—face significant challenges. PHJs often suffer from limited exciton dissociation in thick films, while BHJs experience considerable charge transport barriers. Although quasi-planar heterojunctions have been proposed to address these issues, controlling their nanoscale interface remains complex and material-dependent, limiting their applications. Herein, we introduce novel interpenetrated heterojunctions (IPHJs), formed by penetrating a secondary organic semiconductor layer into a porous bottom layer during annealing. This innovative structure is revealed to possess efficient exciton dissociation and charge transport. Remarkably, organic photodiodes (OPDs) featuring PM6:N2200 IPHJs demonstrate exceptional performance, achieving a responsivity (R) of 36.5 A/W, a specific detectivity (D*) of 8.6 × 1012 Jones, and a response time (τ) of 30 μs, representing state-of-the-art performance for OPDs. Furthermore, extending the IPHJ concept to tri-layer interpenetrated heterojunctions (T-IPHJs) shows significant promise for organic phototransistor applications. The PM6:N2200 T-IPHJ devices exhibit a responsivity exceeding 44.7 A/W, a D* value reaching 5.23 × 1014 Jones, and a τ of 70 ms.

Here, we present a novel phase segregation strategy to achieve uniformly distributed self-assembled Ni nanofilaments within a BaTiO3 matrix, enabling local deterministic redox reactions for RS, as confirmed by comprehensive structural, local, and macroscopic RS studies. This approach yields drastic enhancement in cyclic performance and device uniformity, with the average cyclic variances of Set voltage and low resistance state down to 1.4% and 9.6%, respectively. The devices also exhibit excellent endurance (109 cycles) and ultrafast programming speed (down to 100 ns) and achieve over 5-bit level long-term memory states. The enhanced cyclic stability and device uniformity translate to high training and learning accuracies (95%) in a three-level deep neural network, with 1-bit inputs.
