Abstract
Crossections of MOCVD grown GaAs/GaAlAs double heterojunction structures are investigated by TEM. The substrate/epilayer interface is found to be the main source for defects such as stacking fault 'pyramids', dislocations and dislocation loops. Possible causes for the defect formation, namely contamination of the substrate, excess A L-SCRIPT and lattice mismatch are discussed.
