| 摘 要： | 讨论了超晶格电子无阻尼Bloch振荡过程中的能量转化与守恒，并对其机制以及负电阻效应给以定性解释。结果表明：超晶格电子在任一时刻的能带能量的增加（或减小）等于电子静电位能的减小（或增加），超晶格电子的总能量在振荡过程中保持不变，能量守恒与转化对超晶格负阻效应产生重要影响。

| Abstract: | The energy transformation and conservation of the superlattice electrons in the course of the Bloch oscillation without damping are discussed and the mechanism is given. The results show that the increasing or decreasing of the energy is equal to the decreasing or increasing of the electron electrostatic potential energy. The total energy in the superlattice doesn't vary in the course of the Bloch oscillation in any time. The energy transformation and conservation cause important influence on the negative resistance in the superlattice. |
