Sublimation mechanisms of (100) and (111) CdTe

The sublimation activation energies of (100) and (111)B CdTe have been determined by reflection high energy electron diffraction oscillation measurements. An interpretation of the data is proposed, assuming that the sublimation can be described in both cases by a two-step mechanism. In the explored temperature range, the sublimation kinetics are governed by a common process, leading to a unique activation energy value of 1.90±0.05 eV.
