Paper Abstract

Crystallization velocities and activation energies in the initial crystalli- zation process, obtained from measurements transmissivity(reflectivity), are de- scribed for amorphous In-Sb-Te films 400-600 A thick, which are set up in a chamber with a window guiding of the light through a long-distance focused lens. The crystallization velocity was obtained to about 100 Ajs for Inx(Sb0.4Teo.6)1-. x=0.2--0.3) films. The activation energy was determined by Kissinger's plot to be 1.5--2.0 eV. The frequency factor was calculated by the Johnson-Mehl-Avrami equation; logi 0 v 0=20-30 (Hz). Static repetition cycles of about 3 X 104 were recognized in the film composition of x = 0.2 for the sample structure without upper protection layer.
