About this document
Room-Temperature Spin Injector in MgO by spanishram is a document available to read on EtoBox.
1) Researchers developed a room-temperature spin injector using a crystalline MgO(100) tunnel barrier and ferromagnetic CoFe electrode. 2) Optical measurements on GaAs/AlGaAs quantum well detectors revealed a spin polarization of 57% at 100 K and 47% at 290 K with a magnetic field. 3) Taking spin relaxation effects into account, the estimated spin injection efficiency was at least 52% at 100 K and 32% at 290 K, demonstrating efficient spin injection up to room temperature using this material system.
