Manipulation of the Spin Memory of Electrons in n-GaAs
R. I. Dzhioev, V. L. Korenev, I. A. Merkulov +4
We report on the optical manipulation of the electron spin relaxation time in a GaAs based heterostructure. Experimental and theoretical study shows that the average electron spin…
Electron spin relaxation by nuclei in semiconductor quantum dots
I. A. Merkulov, Al. L. Efros, M. Rosen
We have studied theoretically the electron spin relaxation in semiconductor quantum dots via interaction with nuclear spins. The relaxation is shown to be determined by three proce…
Giant negative magnetoresistance in semiconductors doped by multiply charged deep impurities
S. D. Ganichev, H. Ketterl, W. Prettl +4
A giant negative magnetoresistance has been observed in bulk germanium doped with multiply charged deep impurities. Applying a magnetic field the resistance may decrease exponentia…
