Energy Band and Thermodynamics

B. V. Karpenko, A. V. Kuznetzov, V. V. Dyakin

摘要:

在紧束缚近似下,研究了晶体中各种热力学函数随能带占有度和温度的变化规律。计算了费米能、态密度、简并温度、化学势、配分函数、热力学势、能量、自由能、熵、热容、自旋磁化强度和初始磁化率。与自由电子气体相比,有限的能谱导致这些量的行为的特殊性。

英文摘要:

The behavior of various thermodynamic functions in the dependence of degree of energy band occupation and temperature in the one-band tight binding approximation for the crystal was studied. The Fermi energy, density of states, degeneracy temperature, chemical potential, partition function, thermodynamic po-tential, energy, free energy, entropy, heat capacity, spin magnetization and initial susceptibility were calculated. The limited energetic spectrum leads to the peculiarities in the behavior of these quantities in comparison with free electron gas.
