- Аннотация: The effects of the major growth parameters (thermal conditions, pressure, vapor composition, and growth charge composition) on growth rate and morphology are studied for germanium telluride crystals grown by closed-system sublimation. Growth kinetics were characterized by in situ measurements of the linear crystal size. Growth rate was also assessed from gravimetry data. The ranges of growth parameters were identified in which the process is controlled by vapor transport or proceeds in a mixed (mass transport + condensation) regime. The calculated growth rates agree well with experiment. Estimates based on our results yield a = (2.2 +/- 0.4) x 10(-3) for the effective condensation coefficient and D-0(GeTe/Ar) = 1.48 +/- 0.06 cm(2)/s for the effective diffusion coefficient in the vapor phase.
