Here, we design an interdigital-electrode solar-blind UV β-Ga2O3 photodetector by using high-work function metal Pd as contacts. The atomic transmission electron microscopy data reveal that the Pd-Ga2O3 interface is clean and smooth, composed of a Ga2O3 single crystal and a local Pd single crystal, beneficial for weakening Fermi-level pinning. A low-damage and low-defect contact interface provides an excellent photoelectric response time of 2.4 ms (rise)/2.6 ms (descend) and a large linear dynamic range of 140 dB.

However, the NF performance of these lamellar membranes is severely limited by the irregularity of the nanochannels and the stacking defects of the nanosheets. To address this issue, a facile approach was proposed in this study, which involved the modification of lamellar MXene membranes intercalated with Ag nanoparticles (Ag@MXene) using tea polyphenols (TPs). Upon the TP modification, the initial wrinkles present in the MXene nanosheets were flattened, which effectively reduced the stacking defects and increased the regularity of the nanochannels. Consequently, the water permeability of the TP-modified Ag@MXene (Ag@MXene-TP) membrane significantly increased up to 137.7 Lm−2 h−1·bar−1, a value that was three times the permeability of the pristine MXene membrane. Importantly, the Ag@MXene-TP membrane maintained a high dye rejection rate, with values of 95.85% for Rhodamine B and 97.30% for Congo Red. Molecular dynamics simulations further elucidated the underlying mechanism for the water permeability enhancement. It was found that the adsorption of TPs on the MXene surface prevented the aggregation of MXene nanosheets by shielding the electrostatic attraction between the MXene nanosheets and the Ag nanoparticles. In addition, the enhanced regularity of the nanochannels was also found to cause largely reduced water transport resistance. This pre-modification strategy of MXene nanosheets with TPs provides a new way to build MXene-based nanochannels with improved regularity for high-performance NF membranes.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"36 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945969","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 manufacturability of device quality β-Ga2O3 epitaxial films at scale is urgently needed. Using a production-ready closed-coupled showerhead MOCVD reactor with in situ reflectance monitoring, this study presents a detailed investigation of the impact of growth parameters on the epitaxial growth of β-Ga2O3 on both (010) and (001) oriented native substrates, as well as on c-plane sapphire substrates with 0°–8° off-axis orientations. By tuning the showerhead–susceptor gap and mapping the other growth parameters, including annealing, nucleation, growth temperature, reactor pressure, and substrate orientation, we achieved state-of-the-art crystal quality, extraordinary wafer-level thickness uniformity of &lt;1% variation for both 2-in. and 4-in. substrates for growth rates as high as 7.2 μm/h. All growth was performed using TMGa and pure O2 as the precursors and N2 as the carrier gas instead of the more widely used argon; no detectable nitrogen and carbon incorporation was observed by secondary ion mass spectrometry. For the homoepitaxy of Si-doped β-Ga2O3 films on (010) substrates, a room temperature Hall mobility of 148 cm2/V s was achieved at a carrier concentration of 1.26 × 1017 cm−3, with a growth rate of 2.6 μm/h. For the heteroepitaxy on sapphire, off-axis substrates exhibited enhanced crystallinity, as shown by the continued reduction of x-ray diffraction rocking curve full width at half maximum from 2834 to 1300 arcsec for 0° and 8° offcut sapphire substrates, respectively. The results demonstrate the scalability and potential advantages of this reactor design for manufacturing-scale β-Ga2O3 growth and offer new insights into the controllability of uniform high-quality films for power electronics applications.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"148 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143946066","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 study, a single crystal of Mg4.8Ag1.4Sb4 has been successfully synthesized, demonstrating an ultralow thermal conductivity of approximately 0.6 W m−1 K−1 at room temperature. Structure determination based on single-crystal x-ray diffraction analysis identifies the Fm3¯m space group and the mixed occupancy of Mg atoms (∼60 at. %), Ag atoms (∼17.5 at. %), and vacancies (22.5 at. %) at the 8c site. These crystallographic site-occupation disorders lead to substantial phonon scattering, which is the primary cause of the observed low thermal conductivity. First-principles calculations reveal high anharmonic scattering rates and short mean free paths in Mg4.8Ag1.4Sb4. Complementary molecular dynamics simulations demonstrate the anomalous atomic vibrations of Ag atoms with large amplitudes at 300 K, which induces a low-lying acoustic phonon branch and enhanced phonon density of states at 0.6 THz. This phenomenon accounts for the enhanced anharmonic scattering rates at elevated temperatures, inducing a further reduction in the lattice thermal conductivity. Our work can shed new light on the discovery of novel materials with low thermal conductivity.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"55 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143945606","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}

They can be used to generate unique identities, linked to their structure, by measuring features associated with them. Optically read PUFs (O-PUFs) are a subset that utilizes optical imaging techniques to create these database of identities. They offer a promising solution to the perpetual challenge of counterfeiting by providing a robust authentication solution. The metrics chosen for evaluation are varied across the field; there is a lack of consensus in the figures of merit used for evaluation, as well as the protocols and standards used for assessing this specific subset of PUFs. This work reviews the progress in the development of evaluation techniques to date, and it highlights important differences in the statistical assessment of O-PUFs. A summary of the most popular metrics used in the literature in the past decade is presented, and the core metrics are isolated and mathematically defined. These are then distilled into recommendations of best practice for assessing and comparing different technologies. An open-source package, providing a full testing suite, is presented to standardize testing in this field. Finally, novel methods for evaluating the performance of O-PUFs over time are also proposed.

More importantly in practice, WVM has shown an unprecedented impact on precision sensing. In this review, we begin by presenting the fundamental theory of WVM based on quantum parameter estimation, from which the effects of weak-value amplification and weak-coupling amplification can be derived. The two effects can significantly improve the precision in various sensing schemes based on WVM. We point out the technical advantages that enable the WVM schemes to outperform the conventional ones under the same measurement conditions. Notably, the capability of information compression is underscored, which is garnering increasing attention in the field of quantum metrology. This review aims to show the possibility for broadening the application of WVM to address more critical problems, and on the other hand, for leveraging its advantages to accomplish tasks that are currently unattainable, such that WVM could play a more important role in the future of precision sensing.","PeriodicalId":8200,"journal":{"name":"Applied physics reviews","volume":"47 1","pages":""},"PeriodicalIF":15.0,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143915434","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}

Here, we proposed an effective Weyl picture to effectively describe the macroscopic transport for topological semimetals with effective Weyl bands and simplified parameters. The essential sign regularity of anomalous Hall and Nernst transports was revealed by connecting to the chiralities of Weyl nodes and carrier types. A generalizable temperature scaling was verified by experimental transports of magnetic topological materials. Upon a double-Weyl picture, a concept of Berry-curvature ferrimagnetic structure, as an analogy to the real-space magnetic structure, was further proposed and well described the emerging sign reversal of Nernst thermoelectric transports in temperature scale.
