Abstract :
In this paper, the structural and electronic properties of Cs adsorption on GaAs surface were studied. The samples were prepared by MBE. The conduction bands, valence bands, band structure and density of states were calculated by first principles based on density functional theory. The effect of Zn doping on electronic structure were also analyzed.
