Abstract

The properties of interfaces between highly spin-polarized zinc-blende (ZB) CrAs and GaAs were discussed. The local spin polarization at the Fermi level was high even at ZB-CrAs/GaAs interface. The properties of ZB-CrAs/GaAs where two-monolayer GaAs stack alternately were elaborated. Analysis suggested the use of ZB-CrAs and ZB-CrAs/GaAs multilayers as efficient filter for spin-polarized current injection into GaAs.
