Electrical Spin Pumping of Quantum Dots at Room Temperature
C. H. Li, G. Kioseoglou, O. M. J. van t Erve +7
We report electrical control of the spin polarization of InAs/GaAs self-assembled quantum dots (QDs) at room temperature. This is achieved by electrical injection of spin-polarized…

Analysis of the Transport Process Providing Spin Injection through an Fe/AlGaAs Schottky Barrier
A. T. Hanbicki, O. M. J. van t Erve, R. Magno +7
Electron spin polarizations of 32% are obtained in a GaAs quantum well via electrical injection through a reverse-biased Fe/AlGaAs Schottky contact. An analysis of the transport da…
