Abstract

Defects generated from a thin impurity layer between a CBE-grown epilayer and its GaAs substrate have been studied by TEM. Line defects were observed to emerge randomly from the impurity layer in the various <110> directions either as single lines or as various vshaped dislocation pairs. The origin, frequency and significance of these defects is discussed.
