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 | Abstract: | We 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. | Source: | arXiv, cond-mat/0202131 | Services: | Forum | Review | PDF | Favorites |
