The electrical and optical properties of Janus M2S2ClF and its stress modulation function have been systematically studied by first principles method. The stability of the structure was verified by AIMD. The bandgaps of Janus Al2S2ClF, Ga2S2ClF and In2S2ClF under PBE functional are 2.02, 1.03 and 1.22 eV, respectively. The optical parameters show that the Janus Al2S2ClF exhibits high optical absorption coefficient, low reflectance, and low loss function, which has great potential for application in ultraviolet detection and other optoelectronic devices compared with Janus Ga2S2ClF and In2S2ClF. In the strain range of -4% to 4%, it is found that the light absorption coefficient of Janus Al2S2ClF is significantly changed by strain, and the absorption coefficient under -4% stress is 8.9 times that under 4% stress. Meanwhile, the bandgaps of Janus Ga2S2ClF is significantly changed by stress, which can achieve regulation from 0.47 to 2.57eV. Conclusion that the stress has a significant regulatory effect on its electronic and optical properties, which provides a theoretical basis for realizing high performance and controllable optoelectronic devices. © 2025 SPIE.

The study on the properties of barium carbonate in different crystal systems is play an important role for the evolution of electronic products requiring miniaturization and high performance. Here, the electrical and optical properties of BaTiO3 crystal structures with three space groups (Pm 3 m, P4mm, and P4/mmm) were systematically studied using the first-principles method. The structural are confirmed to be stable by the Born criterion The evolution energy band structures under HSE06 functional were more consistent with other theoretical and experimental results compared to the PBE functional. The band gaps of BaTiO3 for Pm 3 m, P4mm, and P4/mmm space groups up to 3.42, 3.24, and 3.26 eV and exhibit indirect semiconductor behavior. The optical parameters show that the light absorption rate and loss function of all three BaTiO3 were almost zero in the lower energy range. However, the tetragonal phase BaTiO3 with P4/mmm space group has a lower light reflection rate and higher light refractive index compared to the tetragonal phase BaTiO3 with P4/mmm and the cubic phase BaTiO3 with Pm 3 m space group, indicating its potential application value in electro-optic modulation. © 2024 SPIE.

glass enamel coatings are widely used to protect metal against corrosion and weathering due to their exceptional chemical stability. However, the application potential of enamel coatings will be further enhanced if their mechanical properties, particularly impact resistance and toughness, can be improved. In this study, we investigated the influence of varying amounts of alumina fibers on the microstructure, phase composition, and mechanical properties of enamel coatings by fabricating composite enamel coatings. The impact strength, hardness and modulus of the resulting materials were evaluated by falling ball impact tests and nanoindentation tests. The results showed that the alumina fibers were well bonded to the enamel matrix, and the coating surface roughness and contact angle increased with fiber addition. The coating had the lowest porosity and best impact resistance at 0.5 wt% fiber addition. At this point, the modulus and hardness of the composite enamel coating demonstrated improved stability, with the overall hardness reaching its maximum value, and excessive addition of alumina fibers can lead to a reduction in coating performance. As a result, the alumina fibers appear feasible to use as reinforcing material to produce high performance composite enamel coatings. © 2025 Elsevier Ltd and Techna Group S.r.l.

Fabrication of Ultra-Low Absorption Thin Films via Ion Beam Assisted Electron Beam Evaporation

引用

High Power Laser Science and Engineering 2025年

作者： Song, Ruichen Hu, Jiaqi Peng, Yunqi Xiao, Yingao Wang, Yuxiang Zhu, Kongxu Jiang, Yuheng Xia, Xusheng Xia, Zhilin Wuhan University of Technology State key laboratory of advanced glass materials Wuhan China Wuhan University of Technology Material Science and Engineering Wuhan China

High-power laser systems require thin films with extremely low absorption. Ultra-low absorption films are often fabricated via ion beam sputtering, which is costly and slow. This study analyzes the impact of doping titanium and annealing on the absorption characteristics of thin films, focusing on composition and structure. The results indicate that the primary factor influencing absorption is composition. By suppressing the presence of electrons or holes that do not form stable chemical bonds can significantly reduce absorption;For amorphous thin films, the structural influence on absorption is relatively minor. Thus, composition control is crucial for fabricating ultra-low absorption films, while the deposition method is secondary. Ion beam assisted electron beam evaporation, which is relatively seldom used for fabricating lowabsorption films, was employed to produce high-reflectivity films. After annealing, the absorption at 1064 nm reached 1.70 ppm. This method offers a cost-effective and rapid approach for fabricating ultra-low absorption films. © The Author(s), 2025.

Investigating the Growth Behavior of Titanium Dioxide Film Prepared with Direct Current Pulsed–Magnetron Sputtering technology

作者： Zhang, Yi Hao, Yuji Yao, Tingting Wanyu, Ding Dalian Jiaotong University Dalian116028 China CNBM Bengbu Design & Research Institute for Glass Industry Co. Ltd Bengbu233018 China State Key Laboratory of Advanced Technology for Float Glass Bengbu233018 China

The magnetron sputtering technology is employed to deposit amorphous TiO2 film onto Si(100) substrates, which is supplied by a direct current pulsed power unit. After annealing treatment, TiO2 film displays anatase (001) preferential orientation. The growth behavior of deposited and annealed TiO2 films is investigated using atomic force microscope technology. The results show that in the original stage, TiO2 film growth behavior is in Volmer–Weber mode, which is dominated by the diffusion effect. Considering the rivalry between TiO2 crystal nuclei, both crystallographic orientation and diffusion effects jointly dominate the film growth behavior in the rest stage. More importantly, the annealing treatment resulted in the coalescence of TiO2 crystal nuclei, as well as the growth of TiO2 crystal nuclei. Most importantly, after coalescence and growth of TiO2 nuclei, the anatase [001] crystal orientation of TiO2 grains remains the same as the normal direction of TiO2 film. Finally, after annealing treatment, TiO2 films comprise anatase (001) preferential orientation. © 2024, The Authors. All rights reserved.
