摘要

考虑了电子-声子相互作用耦合的两个离散电子能级系统的隧穿问题。分析了弹性和非弹性隧道通道在弱电子-声子耦合和强耦合情况下的相互作用。结果表明,隧道电导率峰的强度和宽度受到非平衡效应的强烈影响。

Effects of electron-phonon interaction in tunneling processes in nanostructures
Tunneling through a system with two discrete electron levels coupled by electron-phonon interaction is considered. The interplay between elastic and inelastic tunneling channels is analyzed not only for weak electron-phonon coupling but also for strong coupling in the resonant case. It is shown that the intensity and width of peaks in the tunneling conductivity is strongly influenced by nonequilibrium effects.
