A model is developed which rationalizes the change in step structure caused by Te doping. Loss of CuPT ordering are caused by high adatom sticking coefficient at the monolayer [100] steps formed due to Te doping. The elimination of 3D mounds on the surface during growth are also observed, since steps are present due to unintentional substrate misorientation. The change in the relative sticking coefficients at up and down steps due to the transition from bilayer steps terminated by (2×2) reconstructed surfaces to monolayer steps are responsible for the reduction in step bunching.
