Abstract

In this work, we investigated the well width dependence of dynamic nuclear polarization in n-GaAs/Al 0.3Ga 0.7As (110) quantum wells. We prepared a set of samples with different well width and thus different g-factor, and measured the degree of dynamic nuclear polarization in these samples by time-resolved Faraday rotation measurements. Our calculation, considering simply the projection of time-averaged electron spins along the external magnetic field, reproduced overall shapes of the nuclear fields as a function of anisotropy of g-factor.
