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.
