论文摘要
我们报告了在Fabry-Pérot和Kondo限制之间运行的纳米版本运输特性中有趣的行为的观察。使用超高质量的纳米管设备，我们研究电导在扫地电压时如何振荡。出乎意料的是，我们观察到温度降低时振荡周期的增强四倍，这表明了从单电子隧道到Fabry-Pérot干扰的交叉。这些结果表明，Fabry-Pérot的干扰发生在电子相关的方向上。讨论了所测得的相关的Fabry-Pérot振荡与SU（4）近藤效应之间的联系。
We report the observation of an intriguing behaviour in the transport properties of nanodevices operating in a regime between the Fabry-Pérot and the Kondo limits. Using ultra-high quality nanotube devices, we study how the conductance oscillates when sweeping the gate voltage. Surprisingly, we observe a four-fold enhancement of the oscillation period upon decreasing temperature, signaling a crossover from single-electron tunneling to Fabry-Pérot interference. These results suggest that the Fabry-Pérot interference occurs in a regime where electrons are correlated. The link between the measured correlated Fabry-Pérot oscillations and the SU(4) Kondo effect is discussed.
