ABSTRACT
The effective "spin-orbit" field acting upon spins of carriers in two-dimensional electronic structures (the Rashba field) arises due to the spatial asymmetry of the system. It will be shown in this letter that even in quantum wells with perfectly symmetric environment, a random Rashba field arises due to fluctuations of concentration of dopant ions. The magnitude of the field, its correlation function, and electron spin relaxation rate in this field are presented.

    We investigate the feasibility of compensating the bulk inversion asymmetry in a [111]-oriented quantum well with the Rashba structure inversion asymmetry that has precisely the same functional form. The resulting cancellation is found to provide a promising means for strongly suppressing the...

    We report on linear and nonlinear short-wavelength (λ<2 μm) intersubband (ISB) absorption characteristics in ZnSe/BeTe quantum wells by means of an interband pump and ISB pump/probe technique. The ISB absorption saturates with a hole burning effect, indicating the absorption band is...

    Intraband relaxation time is investigated theoretically for a wurtzite InGaN/GaN quantum well (QW) with a (101¯0) crystal orientation. The results are compared with those of (0001)-oriented QW structures. It is found that the linewidths for the h–h scattering of the (101¯0)-oriented...
