Ab initio dipolar electron-phonon interactions in two-dimensional materials
Tianqi Deng, Gang Wu, Wen Shi +3
We develop an ab initio formalism for dipolar electron-phonon interactions (EPI) in two-dimensional (2D) materials. Unlike purely longitudinal Fröhlich model, we show that the out-…
Phonon soft modes and para- to ferroelectric phase transitions
Jian-Sheng Wang
In this special issue of Physica A in memory of Professor Dietrich Stauffer, I first recall my impression on him while being his postdoc for a year at HLRZ. In the following scient…
Highly Anisotropic Electronic and Mechanical Properties of Monolayer and Bilayer As2S3
Xuefei Liu, Zhaofu Zhang, Zhao Ding +4
Anisotropic materials, with orientation-dependent properties, have attracted more and more attention due to their compelling tunable and flexible performance in electronic and opto…
Large Contribution of Quasi-Acoustic Shear Phonon Modes to Thermal Conductivity in Novel Monolayer Ga2O3
Gang Liu, Zhaofu Zhang, Hui Wang +2
Bulk gallium oxide (Ga2O3) has been widely used in lasers, dielectric coatings for solar cells, deep-ultraviolet transistor applications due to the large band gap over 4.5 eV. With…
Far-field heat and angular momentum radiation of the Haldane model
Yong-Mei Zhang, Jian-Sheng Wang
We investigate the radiation of energy and angular momentum from 2D topological systems with broken inversion symmetry and time reversal symmetry. A general theory of far-field rad…
Current-induced phonon Hall effect
Kangtai Sun, Zhibin Gao, Jian-Sheng Wang
Since the first experimental observation of the phonon Hall effect (PHE) in 2005, its physical origin and theoretical explanation have been extensively investigated. While spin-orb…
