Abstract
Combined magnetotransport and cyclotron-resonance experiments in a two-dimensional hole system at a modulation-doped GaAs-(AlGa)As heterojunction show that the Kramers degeneracy of the lowest subband is lifted for finite giving rise to two cyclotron masses and at meV. The observation of plateaus in shows that the quantized Hall effect is independent of the details of the host band structure.
