摘要:
The conditions for the occurrence of off-center atomic displacements in pure zinc-blende semiconductors have been studied. A coupling of a chemically active valence d band with an s-like conduction band is predicted to lead to such a metastability. Total energy calculations confirm that this is the case in CuCl and CuBr. The unusual experimental manifestations of this metastability are outlined.
