The Warm Electron Coefficient in n‐InSb in the Presence of a Quantizing Magnetic Field at Low Temperatures

The warm electron coefficient (β) in n‐InSb in the presence of a quantizing magnetic field at low temperature is investigated theoretically to interpret the experimental results in n‐InSb at T L = 4.2K. The theoretical model used for the calculation of β considers the displaced Maxwellian distribution for electrons and other complexities such as the band nonparabolicity, the non‐equipartition of phonons, the free‐carrier screening, and the Landau‐level broadening. The theoretical results of β obtained by the above model are found to agree qualitatively with the experimental results taking the standard material parameters of n‐InSb. To fit the theoretical values of β with the experimental values, the acoustic deformation potential constant ( E 1 ) is found to be 13 eV which agrees with other observations.
