Abstract
Cathodo- and photoluminescence of MnF2 thin epitaxial layers and MnF2-CaF2 superlattices on Si(1 1 1) has been studied at low temperatures. A blue shi ft of the main Mn2+ broad band in MnF2 films thinner than three monolayers is revealed. The shift is likely to be due to the change of the crystal str ucture from the tetragonal rutile-type characteristic of bulk crystals and thick layers to the cubic fluorite-type structure, as measured by RHEED and EXAFS.
