摘要

We report on measurements of the drag effect between coupled two-dimensional hole gases. We investigate the coupling by changing the carrier densities in the quantum wells, the widths of the barriers between the gases, and the perpendicular magnetic field. We make use of the nonparabolicity of the hole-dispersion curves to tune the Fermi wave vector and the Fermi velocity separately. With this technique we find that the frictional drag is mainly due to phonon coupling.
