Giant Spin Lifetime Anisotropy and Spin-Valley Locking in Silicene and Germanene from First-Principles Density-Matrix Dynamics
Junqing Xu, Hiroyuki Takenaka, Adela Habib +2
Through First-Principles real-time Density-Matrix (FPDM) dynamics simulations, we investigate spin relaxation due to electron-phonon and electron-impurity scatterings with spin-orb…

Substrate Effect on Excitonic Shift and Radiative Lifetime of Two-Dimensional Materials
Chunhao Guo, Junqing Xu, Yuan Ping
Substrates have strong effects on optoelectronic properties of two-dimensional (2D) materials, which have emerged as promising platforms for exotic physical phenomena and outstandi…
