Time-Dependent Density Functional Theory Simulation for Analyzing Neutralization Process of Hydrogen Ion Injected onto Tungsten Surfaces
Abstract
We have performed time-dependent density functional theory simulations for the neutralization process of a hydrogen ion injected at 100eV onto the (110) surface of tungsten material. We have also proposed a method for evaluating the detection probability of electrons in a small region. This probability is interpreted as that of detecting hydrogen in each state: positive ion, neutral atom, and negative ion. As a result, the probabilities of detecting hydrogen after a collision as a positive ion, neutral atom, and negative ion were approximately 30 percent, 50 percent, and 20 percent, respectively.
