The problem of the valence band structure and effective masses in III‐V compounds is analysed. It is shown that the linear terms in the energy of heavy holes are of importance and cannot be neglected. The density‐of‐states effective mass of heavy holes is calculated as a function of the temperature and position of the Fermi level. The cyclotron‐resonance effective masses are also calculated for the limiting cases of heavy holes with low and high energies. The influence of the higher bands on the nonparabolicity of the conduction and light‐hole valence band is discussed. The effective mass of electrons and light holes as a function of concentration is calculated. The band parameters are determined by using the method proposed by Cardona [1].
