Abstract

Due to its p-like character, the valence band in GaAs-based heterostructures offers rich and complex spindependent phenomena. One manifestation is the large anisotropy of Zeeman spin splitting. Using undoped, coupled quantum wells (QWs), we examine this anisotropy by comparing the hole-spin dynamics for high-and low-symmetry crystallographic orientations of the QWs. We directly measure the hole g ...
