The electron effective mass in n‐type HgTe is found for concentrations between 5 × 10 17 and 6 × 10 18 cm −3 by measurements of the thermoelectric power in a magnetic field. The effective mass is strongly dependent on the electron concentration. This dependence can be explained by using Kane's model with the parameters m n / m 0 = 0.018, ε 0 = 0.21 eV. In the investigated samples the dominant electron scattering is due to ionized impurities.
