Spintronic devices and method for injecting spin-polarized electrical currents into semi-conductors

摘要

Atomically ordered interfaces between semiconductor and ferromagnetic materials provide spin filters. The spin filters may be used to inject strongly spin polarized currents into a semiconductor for use in spintronic devices. Some suitable combinations of ferromagnetic metal and semiconductor include hcp Co or fcc Ni or fcc Co (ferromagnetic metals) interfaced to GaSb, InAs, ZnTe, CdSe or GaAs or InP or Ge or BN or semiconductor alloys that include any of these (semiconductors).
