摘要：

The electronic structure and the ferromagnetism of V- and Cr-doped zinc-blende semiconductor CdTe have been investigated by spin-polarized calculations with first-principles plane-wave pseudopotential method within the generalized gradient approximation for the exchange-correlation potential. We find that the V- and Cr-doped zinc-blende CdTe show half-metallic behavior with a total magnetic moment of 3.0 and 4.0 mu(B) per supercell, respectively. It may be useful in semiconductor spintronics and other applications. (c) 2005 Elsevier B.V. All rights reserved.
