Non-magnetic semiconductor spin transistor
K. C. Hall, Wayne H. Lau, K. Gundogdu +2
We propose a spin transistor using only non-magnetic materials that exploits the characteristics of bulk inversion asymmetry (BIA) in (110) symmetric quantum wells. We show that ex…
Nuclear Spin Dynamics in Parabolic Quantum Wells
I. Tifrea, Michael E. Flatte
We present a detailed analytical and numerical analysis of the nuclear spin dynamics in parabolic quantum wells. The shallow potential of parabolic quantum wells permits substantia…
Multiband tight-binding model of local magnetism in GaMnAs
Jian-Ming Tang, Michael E. Flatte'
We present the spin and orbitally resolved local density of states (LDOS) for a single Mn impurity and for two nearby Mn impurities in GaAs. The GaAs host is described by a sp^3 ti…
Spin relaxation in (110) and (001) InAs/GaSb superlattices
K. C. Hall, K. Gundogdu, E. Altunkaya +6
We report an enhancement of the electron spin relaxation time (T1) in a (110) InAs/GaSb superlattice by more than an order of magnitude (25 times) relative to the corresponding (00…
