- Title
Spin Relaxation in the Quantized Hall Regime in the Presence of Disorder.
- Authors
Dickmann, S.
- Abstract
We study the spin relaxation (SR) of a two-dimensional electron gas in the quantized Hall regime and discuss the role of spatial inhomogeneity effects on the relaxation. The results are obtained for small filling factors (ν<1) or when the filling factor is close to an integer. In either case, SR times are essentially determined by a smooth random potential. For small ν, we predict a “magneto-confinement” resonance manifested in the enhancement of the SR rate when the Zeeman energy is close to the spacing of confinement sublevels in the low-energy wing of the disorder-broadened Landau level. In the resonant region, the B-dependence of the SR time has a peculiar nonmonotonic shape. If ν≃2n + 1, the SR is going nonexponentially. Under typical conditions, the calculated SR times range from 10[sup –8] to 10[sup –6] s. © 2003 MAIK “Nauka / Interperiodica”.
