First-Principles Studies the Lattice Constants and the Electronic Structures of Diluted Magnetic Semiconductors (In, Mn)As

摘要

Lattice constants and electronic structures of diluted magnetic semiconductors (In, Mn) As were investigated using the first principles LMTO-ASA band calculation by assuming supercell structures. Three concentrations of the 3d impurities were studied (x = 1/2, 1/4, 1/8). The effect of varying Mn concentrations on the lattice constants and the electronic structures are shown.
