We report on experimental and theoretical investigations of the cyclotron mass in six n-type modulation doped HgTe single quantum wells. Magnetotransport measurements at low temperatures resulted in well pronounced Shubnikov-de Haas oscillations and quantum Hall plateaus. The cyclotron mass was determined from the temperature dependence of the Shubnikov-de Haas oscillations at low magnetic fields. Theoretical calculations of the semi-classical cyclotron mass are based on a 8 × 8 k · p model. The influence of the induced free carriers is included in a self-consistent Hartree calculation.
