We demonstrate experimentally and theoretically that two-dimensional (2D) heavy-hole systems in single heterostructures exhibit a decrease in spinorbit interaction-induced spin splitting with an increase in perpendicular electric field. Using front and back gates, we measure the spin splitting as a function of applied electric field while keeping the density constant. Our results are in contrast to the more familiar case of 2D electrons where spin splitting increases with electric field.

axis, which would allow a direct comparison of the measured and calculated results, is very hard to define because of uncertainties in the sample parameters. - F. Stern,
