摘要:

本文研究了高迁移率二维电子系统中声子诱导电阻振荡的温度依赖性。我们观察到,温度依赖性是非单调的,高阶振荡最好在逐渐降低的温度下发展。我们的分析表明,与Shubnikov-de Haas效应相反,声子诱导的电阻振荡对电子-电子相互作用的改变是敏感的。

英文摘要:

We report on temperature dependence of acoustic phonon-induced resistance oscillations in very high mobility two-dimensional electron systems. We observe that the temperature dependence is non-monotonic and that higher order oscillations are best developed at progressively lower temperatures. Our analysis shows that, in contrast to Shubnikov-de Haas effect, phonon-induced resistance oscillations are sensitive to electron-electron interactions modifying the single particle lifetime.
