Abstract
We demonstrate single electron shuttling through two coupled nanomechanical pendula. The pendula are realized as nanopillars etched out of the semiconductor substrate. Coulomb blockade is found at room temperature, allowing metrological applications. By controlling the mechanical shuttling frequency we are able to validate the different regimes of electron shuttling.
摘要
我们展示了通过两个耦合的纳米机械摆来实现单电子输运。这些摆由半导体衬底中刻蚀出的纳米柱实现。在室温下发现了库仑阻塞，从而允许进行计量学应用。通过控制机械输运的频率，我们能够验证电子输运的不同状态。
