Cyclotron resonance of the two-dimensional hole gas (2DHG) in the strained-layer quantum well structure of In0.20Ga0.80As/GaAs is observed in far-infrared transmission measurements made at 4.2 K. The cyclotron mass of the 2DHG in the In0.20Ga0.80As channel is (0.191±0.008)me for a 2D hole density p2D =8.5×1011/cm2.
