- Abstract
We have measured the circular photogalvanic effect in a GaAs two-dimensional hole gas in zero and perpendicular magnetic field. The increase of the photoinduced voltage in very small magnetic field, when excited at fixed photon energy, demonstrates behavior reminiscent of that seen in anomalous Hall measurements on ferromagnets. The spectral dependence of the photoinduced voltage in magnetic field exhibits a series of maxima and minima that oscillate around zero volts. When plotted, the energy positions of these voltage peaks form a clear Landau-level-like fan chart.
