Abstract
It has long been assumed that the inversion asymmetry-induced Rashba spin splitting in two-dimensional (2D) systems at zero magnetic field is proportional to the electric field that characterizes the inversion asymmetry of the confining potential. Here we demonstrate, both theoretically and experimentally, that 2D heavy hole systems in accumulation-layer-like single heterostructures show the opposite behavior; i.e., a decreasing, but nonzero electric field results in an increasing Rashba coefficient.Keywords
