Here, we present a universal sub-micrometer fabrication method for mesoscopic devices using a dry-transfer technique, tailored specifically for sensitive materials. This approach utilizes PMMA masks, combined with a water-dissoluble coating as a sacrificial layer, to ensure that sensitive materials are processed without exposure to harmful environmental conditions. The entire fabrication process is carried out in a glovebox, employing dry techniques that avoid air, solvents, and heat exposure, culminating in an encapsulation step. We demonstrate the utility of this method by fabricating and characterizing K2Cr3As3 and WTe2 devices, a one- and two-dimensional material, respectively. The results show that our technique preserves the integrity of the materials, provides excellent contact interfaces, and is broadly applicable to a range of sensitive materials.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"626 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 the above-mentioned research related to material anisotropy, it is necessary to determine the crystallographic orientation of thin-layer samples. In this paper, we systematically studied the optical in-plane anisotropy of the layered topological semimetal Nb3SiTe6 via angle-resolved polarized Raman spectroscopy. The Raman intensities of the 13 Raman peaks show clear polarization dependence. Based on the lattice symmetry of multilayer Nb3SiTe6, we accurately distinguished the two Raman modes of Nb3SiTe6 and corresponding Raman peaks. In addition, we proposed a method for quickly, accurately, and nondestructively determining the crystallographic orientation of multilayer Nb3SiTe6 by polarized Raman spectroscopy. This work provides a crucial foundation for exploring potential applications of the anisotropy of Nb3SiTe6 in thermoelectric and optoelectronic fields.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"15 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 strain reconfiguration strategy utilizing a medium-temperature AlN (MT-AlN) interlayer is proposed. By optimizing the MT-AlN thickness at 1000 °C, tensile strain originating from the GaN template is systematically released through interfacial relaxation and lattice redistribution within the interlayer. Additionally, the engineered configuration also establishes a coherent crystalline template with programmable strain states for subsequent epitaxial growth. With a 25-nm optimized interlayer, crack-free Al0.35 ∼ 0GaN multiple heterojunctions are epitaxially grown on the GaN template with slight compressive strain and nearly no additional dislocations. The resultant high-crystallinity AlGaN heterostructures enable the UV photodetector to achieve high responsivity (maximum 1.4 × 103 A/W), ultrafast response speed (0.6/25.4 ns rise/fall time), and remarkable operational stability simultaneously. All these collectively validate the MT-AlN strain reconfiguration as a viable pathway for the advancement of AlGaN-based optoelectronic devices.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"45 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311348","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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 contemporary commercial cesium clocks, two primary approaches are employed: the magnetically selected state scheme and the optical pumping scheme. Here, we propose a magneto-optically pumped cesium beam clock with a frequency stability of 2.3×10−12τ−1/2. In this scheme, the pumping light and state selection magnet are both used for the preparation of atomic states. In the magnetic field of the state selection magnet, the relationship between pumping efficiency and laser frequency, laser power, and laser position has been investigated. Eventually, we find a position that allows the laser to resonate with cyclic transition line |F=3⟩−|F′=2⟩ to pump almost all of the atoms |F=3⟩ to state |F=4⟩. Therefore, we can pump and detect atoms without the use of an AOM. This approach not only combines the advantage of low atomic velocity from the magnetically selected state scheme and the high atomic utilization efficiency from the optical pumping scheme but also simplifies the scheme of optically pumped cesium beam clock. In addition, this physical system can also facilitate the investigation of the shift in cesium atomic energy levels under strong magnetic fields.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"11 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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, these devices encounter challenges arising from defects within the perovskite lattice and at interfaces, which lead to non-radiative recombination and voltage losses. To address these issues, we have developed a synergistic approach that combines bulk passivation using l-cystine dihydrochloride as an additive with subsequent surface passivation treatments. This compound effectively passivates Pb2+ and halide defects through its carbonyl and amine functional groups. Both experimental and simulation results demonstrate that l-cystine dihydrochloride effectively reduces trap states, retards nucleation kinetics, promotes grain growth, and enhances crystallinity. Consequently, the device [FA0.8Cs0.2Pb(I0.6Br0.4)3, energy gap: 1.77 eV] incorporating l-cystine dihydrochloride achieved a power conversion efficiency (PCE) of approximately 16.00%, which was further increased to 17.03% with an additional octylammonium iodide surface passivation. Expanding our approach, we have fabricated the wide bandgap semitransparent device, yielding a PCE of 15.62%. When integrated with narrow-bandgap organic solar cells in four-terminal (4T) perovskite/organic tandem solar cells, a remarkable efficiency of 23.14% was attained. This strategy effectively improves the performance of wide bandgap PSCs, which exhibit great potential in advancing perovskite/organic photovoltaic technologies.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"44 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144311357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
