The effective mass of electrons in the intrinsic region of InSb

The effective masses of electrons m_n/m_oin the intrinsic region are calculated on the basis of measurements of the temperature dependence of the total magnetic susceptibility and the Hall coefficient of single-crystal and polycrystalline specimens of n- and p-type InSb. It is shown that the effective masses m_n/m_oare constant in the range considered and their values for the various specimens are 3·43×10^–2 to 3·53×10^–2.
