Abstract

The effects of thermal treatment on the dependence of optical constants on wavelength and the changes of optical constants of GeTe, Sb₂Te₃ and Ge₂Sb₂Te₅ thin films at different annealing temperatures are studied. It can be found that the optical constants of GeTe, Sb₂Te₃ and Ge₂Sb₂Te₅ thin films change with increasing annealing temperature. The crystallization speed changes with increasing Sb content, i.e.: the crystallization speed of GeTe < the crystallization speed of Ge₂Sb₂Te₅ < the crystallization speed of Sb₂Te₃. The mechanism of the change of the optical constants of the GeTe, Sb₂Te₃ and Ge₂Sb₂Te₅ systems due to thermal treatment is also analyzed.
