Cyclotron resonance at the microwave frequency is used to measure the band edge mass (mb) in the two-dimensional hole (2DH) system, confined in 30 nm quantum wells in the Al0.1Ga0.9As/GaAs/Al0.1Ga0.9As heterostructures. We find that for 2DH density p⩽1.0×1010 cm−2, mb is nearly constant, ∼0.35me. It increases with increasing density, to ∼0.5me at p=7.4×1010 cm−2.
