Paper Abstract

The effect of the deposition rate, the substrate temperature, the annealing temperature, the laser and high energy electron irradiation on the mechanical stresses for the heterostructure obtained by thermal evaporation of Ge33As12Se55 film onto the crystalline p-Si has been investigated. It has been found that the mechanical stresses are the tensile ones and are in the range between 1 X 107 Pa and 1 X 108 Pa dependent on the film structure related to the deposition technique. Special features of the stresses changes at the deposition rate 6.0 nm/s and the substrate and the annealing temperatures 450 K has been revealed. The results have been interpreted in terms of the topological structural transition associated with the transition from the 2D structure to the 3D one.
