D. Labrie et Jj. Dubowski, EVIDENCE FOR THE MINIBAND DISPERSION IN THE PHOTOREFLECTANCE OF A CDTE CD1-XMNXTE SUPERLATTICE/, Superlattices and microstructures, 16(1), 1994, pp. 25-28
We report evidence for miniband dispersion in a CdTe/Cd1-xMnxTe superl
attice by using photoreflectance spectroscopy. In addition to the two
dominant signatures associated with the fundamental heavy- and light-h
ole free exciton transitions occurring within the superlattice, two ve
ry weak resolved signatures are observed at higher energy. A Kronig-Pe
nny type model is used to attribute these signatures to the two lowest
heavy- and light-hole free exciton transitions occurring at the edge
of the Brillouin minizone.
