Electron Spin Injection at a Schottky Contact
J. D. Albrecht ; D. L. Smith ;
Date 8 Feb 2002
Journal Phys. Rev. B 66, 113303 (2002)
Subject cond-mat
AbstractWe investigate theoretically electrical spin injection at a Schottky contact between a spin-polarized electrode and a non-magnetic semiconductor. Current and electron density spin-polarizations are discussed as functions of barrier energy and semiconductor doping density. The effect of a spin-dependent interface resistance that results from a tunneling region at the contact/semiconductor interface is described. The model can serve as a guide for designing spin-injection experiments with regard to the interface properties and device structure.
