摘要：

We report results of density functional theory total energy and force calculations of Te covered GaAs- and InAs(100)-(2 X 1). The adsorption is studied for the coverages of 1/2 and 1 monolayer of Te. The atomic positions of the adsorbate and the three outermost substrate layers are fully relaxed and the equilibrium surface geometries are given. We discuss how the adsorption modifies the dean surface geometry and the electronic structures.
