简并跳跃系统的迁移率和能量输运

Mobility and energy-transport in degenerate hopping systems

Dan Mendels, Nir Tessler

摘要:

回顾电荷输运在简并跳跃系统中,我们提出了一个修改的漂移扩散方程,而不是采用广义爱因斯坦关系,我们增加了一个能量通量项,从而解决了几个不一致。这也导致了这样的结论:与通常的看法相反,恒定的准费米能级并不一定确保零电流。虽然我们重新审视的背景下,退化跳跃系统的漂移扩散过程中,提出的论证的相当一部分可以普遍适用于退化系统。

英文摘要:

Revisiting charge transport in degenerate hopping systems we present a modification to the drift diffusion equation where instead of employing the generalized Einstein relation we add an energy flux term thus solving several inconsistencies. This leads also to the conclusion that, contrary to common belief, a constant quasi-Fermi level does not necessarily ensure zero electrical current. While we revisit the drift diffusion process in the context of degenerate hopping systems, a considerable part of the argumentation put forward can be applied generally to degenerate systems.
