Abstract
The conditions for operation of two multiplication mechanisms in strained layers are analyzed. These are spiral and Frank–Read type sources. It is shown that a minimum thickness is required for their operation, of the order of four times the critical thickness for the bending over of threading dislocations. The implications for strain relief of mismatched layers are discussed.This publication has 13 references indexed in Scilit:
