Saturable absorption in highly excited silicon and its suppression at the surface
Shunsuke Yamada, Tomohito Otobe
Nonlinear electronic excitation in laser-irradiated silicon at finite electron temperatures is numerically investigated by first-principles calculations based on the time-dependent…

Influence of Point Defects on Laser-Induced Excitation in Silicon
Tomohito Otobe, Eiyu Gushiken
We studied the influence of defect states on the laser excitation process in silicon using time-dependent density functional theory. We assumed two types of point defects: intersti…
