Electron stopping power of α-particles in silicon regulated by ultrashort pulse lasers

Abstract

We conducted a study on the electron stopping power of α-particles in silicon crystals regulated by ultrashort pulse lasers, using time-dependent density functional theory non-adiabatically coupled with molecular dynamics. Our investigation focused on α-particles with initial velocities ranging from 0.1 to 1.0 a.u., providing detailed insights into the electronic states involved in the stopping process with exceptional spatial and temporal resolution. Our findings show how laser pulses can influence electron stopping power and the degree to which this stopping power can be controlled by the laser pulses.
