摘要: We investigate the spin dynamics and relaxation in remotely-doped two dimensional electron systems where dopants lead to random fluctuations of Rashba spin-orbit coupling. Due resulting precession, time is limited by strength spatial scale contribution concentrate on role randomness for direction field does not depend momentum: field-effect transistor with balanced Dresselhaus couplings (011) quantum well. Both these are considered as promising spintronics applications because suppression Dyakonov-Perel' mechanism there makes realization a effect diffusive regime possible. demonstrate that through coupling imposes important physical limitations operational properties devices.
