We report direct observations of surface reconstructions on CdTe by high-resolution electron microscopy in the profile-imaging geometry. The predominant surface was (111) which was often found to be twinned. Image simulations confirmed that the (110) reconstruction was similar to that derived from low-energy electron diffraction studies. A metastable 3×n reconstruction was observed on the (100) surface.
