摘要：

We show that a two-dimensional spin system can occur for heavy, mJ=+3/2 holes resulting from a reduction to tetragonal symmetry produced by biaxial strain or confinement in a quantum well. Evidence is produced from magnetotransport measurements on strained Ga1-xInxSb/GaSb quantum wells, in which the spin splitting is determined only by the component of magnetic field in the growth direction, and from published work on unstrained GaAs/AlxGa1-xAs heterojunctions. Complementary behavior is predicted for light holes. © 1990 The American Physical Society.
