The evolution of the CdTe(001) surface during ion bombardment was studied by grazing incidence X-ray diffraction (GIXD) and by Monte Carlo simulation. A layer-by-layer removal was observed at which evolves to a step-flow mode above . An anisotropic relaxation of the surface lattice parameter and a long-distance correlation between islands along the direction were observed during sputtering.
