摘要: 利用费米分布函数和杂质电离的热平衡理论计算了载流子在杂质能级上的占据概率,其结果与传统的热力学统计理论及计算化学势方法得到的结果完全一致.本方法运算简单,且物理意义清晰.

Abstract: The probability functions of carriers occupying the impurity level are calculated by applying the Fermi-Dirac distribution function and the thermal-equilibrium theory of the impurity ionization, the result accord with that obtained by applying the conventional thermodynamic and statistical theory and the method of computing the chemical potential. The new method is very simple, and has very clear physical significance.

Key words: carrier, Fermi distribution function, spin, impurity level
