Impurity effects on generation and motion of dislocations in InP

Effects of impurities on the dynamic activities of dislocations in InP are discussed. It is shown that S impurity enhances the motion of alpha dislocations and retards the motion of beta and screw dislocations. Zn impurity strongly retards the motion of all types of dislocations. Ga and As impurities have little effect on the mobilities of dislocations, but strongly suppress the generation of alpha dislocations.<>
