Understanding all-optical spin switching: Comparison between experiment and theory
G. P. Zhang, M. Murakami, M. S. Si +2
Information technology depends on how one can control and manipulate signals accurately and quickly. Transistors are at the core of modern technology and are based on electron char…
Laser-induced ultrafast demagnetization time and spin moment in ferromagnets: First-principles calculation
G. P. Zhang, M. S. Si, Thomas F. George
When a laser pulse excites a ferromagnet, its spin undergoes a dramatic change. The initial demagnetization process is very fast. Experimentally, it is found that the demagnetizati…
A large enhancement of carrier mobility in phosphorene by introducing hexagonal boron nitride substrate
Jiafeng Xie, Z. Y. Zhang, D. Z. Yang +3
Carrier mobility is a crucial character for electronic devices since it domains power dissipation and switching speed. Materials with certain high carrier mobility, equally, unveil…
Negative Poisson's ratios in few-layer orthorhombic arsenic from first-principles calculations
Jianwei Han, Jiafeng Xie, Z. Y. Zhang +3
A material exhibiting a negative Poisson's ratio is always one of the leading topics in materials science, which is due to the potential applications in those special areas such as…
A theoretical study of blue phosphorene nanoribbons based on first-principles calculations
Jiefeng Xie, M. S. Si, D. Z. Yang +2
Based on first-principles calculations, we present a quantum confinement mechanism for the band gaps of blue phosphorene nanoribbons (BPNRs) as a function of their widths. The BPNR…
Manipulating femtosecond magnetism through pressure: First-principles calculations
M. S. Si, J. Y. Li, D. S. Xue +1
Inspired by a recent pressure experiment in fcc Ni, we propose a simple method to use pressure to investigate the laser-induced femtosecond magnetism. Since the pressure effect on…
