Influence of Vacancy Defect on Surface Feature and Adsorption of Cs on GaN(0001) Surface
The effects of Ga and N vacancy defect on the change in surface feature, work function, and characteristic of Cs adsorption on a 2×2 GaN(0001) surface have been investigated using density functional theory with a plane-wave ultrasoft pseudopotential method based on first-principles calculations. The...
