Abstract

Different possible mechanisms of crystal growth for the used in the practice LPE techniques are considered in the present paper. The time dependences of the super saturation for the cases of normal growth mechanism and screw dislocations growth mechanism are presented. The values of the stationary super saturation, of the stationary growth rate and of the time constant for the transient growth process are obtained. The effect of the initial super saturation on the growth rate is considered. Relation between the stationary value of the super saturation, the time constant of the transient process, the cooling rate and the liquidus surface slope has been ascertained.
