Quantum electron dynamics in helium ion injection onto tungsten surfaces based on time-dependent density functional theory

The neutralization of an ion particle on a surface is a key issue in plasma–wall interactions. We investigated helium ion injection onto a tungsten surface using time-dependent density functional theory (TDDFT) simulations. We developed the TDDFT code QUMASUN and simulated the process of electron tr...
