Oscillatory processes at phase boundaries in zone refining with a temperature gradient in a stationary temperature field

A study is made of the effect of the threshold of kinetic processes on the character of motion of the phase boundaries in a crystal-melt. Numerical results are presented and an analysis made of the conditions under which oscillations arise in the rate of growth of epitaxial layers.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 3, pp. 68–72, March, 1995.
