Abstract

We report on a method to fabricate and measure gateable molecular junctions that are stable at room temperature. The devices are made by depositing molecules inside a few-layer graphene nanogap, formed by feedback controlled electroburning. The gaps have separations on the order of 1-2 nm as estimated from a Simmons model for tunneling. The molecular junctions display gateable I-V-characteristics at room temperature.

摘要

我们报告了一种制造和测量室温下稳定的可门控分子结的方法。这些器件是通过在由反馈控制的电烧蚀形成的几层石墨烯纳米间隙中沉积分子来制备的。根据隧道的 Simmons 模型估计，这些间隙的分离约为 1-2nm。室温下，分子结显示出可门控的 I-V 特性。
