Numerical and analytical results of studying the effect of size quantization of single-particle entropy in a two-dimensional electron gas in semiconductor materials with a nonparabolic conduction band are presented. The dependence of the one-particle entropy on the chemical potential of the gas at resonance point and far from it is analyzed. It is shown that at low temperatures the nonparabolicity of the band gives a small correction to the single-particle entropy. Both at the resonance point and far from it, this correction is proportional to the product of the nonparabolic coefficient and the temperature αT. The influence of the broadening of spatial quantization levels on the single-particle entropy is estimated numerically. The results obtained are presented for different temperatures, the degree of nonparabolicity of the conduction band, and the magnitude of the broadening.
