摘要

High-quality bulk single crystals of pure and Er3+-doped SrLaGa3O7 (SLGO) were grown successfully by the Czochralski method. The crystal structure of SLGO was demonstrated. The theoretical calculations based on density functional theory methods were carried out on the SLGO crystal. Its band structure and density of state were presented. The absorption, up-conversion, near-infrared and mid-infrared fluorescence spectra, as well as the fluorescence decay curves of Er: I-4(13/2) and I-4(11/2) levels of the Er:SLGO crystal were measured at room temperature. The spectroscopic properties including the absorption and emission cross sections as well as the fluorescence lifetimes were revealed. It is concluded that the Er:SLGO crystal is a promising candidate material for achievement of a mid-infrared laser.

First-principles calculation of anomalous Hall and Nernst conductivity by local Berry phase

Hikaru Sawahata, Naoya Yamaguchi, Susumu Minami, Fumiyuki Ishii

Summary: We implemented a finite-difference algorithm to compute anomalous Hall and Nernst conductivity, extending the methods to metallic systems. The calculated results for various ferromagnetic materials are comparable to those obtained using the Kubo formula or Wannier representation. Detailed Fermi-energy dependence is required to evaluate anomalous Nernst coefficients. This method enables efficient thermoelectric material design based on high-throughput first-principles screening.

Huili Li, Ling Fu, Chaozheng He, Jinrong Huo, Houyong Yang, Tingyue Xie, Guozheng Zhao, Guohui Dong

Summary: The adsorption behavior of H2CO on original and Zn-doped monolayer MoS2 was studied using density functional theory. The results showed weak adsorption on original monolayer MoS2 and the formation of a new surface catalyst with high selectivity on Zn-doped monolayer MoS2. Adsorption on Zn-doped monolayer MoS2 exhibited different energy levels and effects on electronic structure based on the orientation of the H2CO molecule.

First Principles Calculation of Al-Doped Mg/Mg2Sn Alloy Interface

Wang Furong, Zhang Yongmei, Bai Guoning, Guo Qingwei, Zhao Yuhong

Summary: Mg-Sn alloy is a potential lightweight automobile material with high temperature-creep resistance. Adding Sn to Mg reduces overall cost, and the formation of Mg2Sn phase improves precipitation hardening. Al-doping significantly enhances the age hardening effect of Mg-Sn alloy due to segregation at the Mg matrix and Mg2Sn phase interface. This study investigates different orientations of Al-doped Mg and Mg2Sn phase to determine stable doping positions through calculations and analyzes the effects of Al doping on the electronic structure of the Mg/Mg2Sn interface. The results indicate that certain Al-doping positions strengthen the stability of the interface, and Al-Sn bonding dominates at the interface.

First-principles calculation of KH2PO4 anharmonic force constants phonon dispersion curves

Guokai Hao, Xin Ju, Xun Sun, Baoan Liu, Lisong Zhang, Yanlu Li, Xiangxu Chai, Lei Wei, Pengcheng Wu, Liening Wei, Yang Li, Mingxia Xu

Summary: In this study, the impact of phonons on the damage process of KDP crystal was explored by studying lattice dynamics. The phonon dispersion curves of KDP crystal with harmonic and anharmonic effects were calculated using first-principles DFT calculations. The results showed that three large imaginary frequencies caused by O-H stretching soft modes were observed in the PE phase with harmonic approximation, which led to the FE-PE phase transition. The imaginary frequency disappeared when considering the anharmonic effect of large displacement vibration of H atoms in the PE phase. These findings have important reference significance for understanding the damage mechanism of KDP crystal.
