Crystal growth in Se70Te30 thin films followed by SEM and in situ XRD
Original language description
The isothermal crystal growth kinetics in Se70Te30 thin films was investigated using the microscopy and in situ X-ray diffraction (XRD) measurements. Plate-like crystals grew linearly with time which is the sign of liquid-crystal interface kinetics. In the studied temperature range, from 68 degrees C to 88 degrees C, crystal growth rates exhibit simple exponential behavior with an activation energy of crystal growth E-G = 168 +/- 12 kJ mol(-1). The growth data obtained from the microscopy measurements were combined with viscosity data, melting parameters and the appropriate crystal growth model was assessed. The relation between the kinetic coefficient of crystal growth and viscosity (u proportional to eta-(xi)) is described in detail, and a correction of the standard growth model is suggested. The crystal growth data obtained from the in situ XRD measurements were described using the Johnson-Mehl-Avrami nucleation-growth model with the Avrami exponent m = 2.2 +/- 0.2. The activation energy of the overall crystallization process EA was estimated and its value is 171 +/- 11 kJ mol(-1). Published by AIP Publishing.
