Transmission electron microscopy and scanning transmission electron microscope analysis of the effects of thermal processing on the structural integrity of GaInAs/GaInAsP multilayers.

Presents a study that reported the structural characterization by electron microscopy of a metalorganic chemical vapor deposition grown GaInAs/GaInAsP multiple-quantum-well structure undergoing a blue shift in luminescence wavelength upon thermal processing, as part of a multistage epitaxial growth process. Experimental details; Results of the study; Details of stem mapping of blue-shifted multilayers.
