我们制造了两个名义上相同的一维小隧道结阵列，每个阵列有10个串联结。一个阵列的每个电极电容耦合到另一个阵列中的两个电极。通过同时测量两个阵列的电流电压特性，我们观察到两个阵列中的电流之间存在耦合。在偏置条件的狭窄区域，我们发现电流同样大，但符号相反。我们将其解释为一个阵列中的电子和另一个阵列中的空穴的相关输运。实验结果与数值模拟结果定性一致。
We have fabricated two nominally identical one-dimensional arrays of small tunnel junctions, each with 10 junctions in series. Each electrode of one array is capacitively coupled to two electrodes in the other array. By measuring the current voltage characteristics of the two arrays simultaneously, we observe a coupling between the currents in the two arrays. In a narrow region of biasing conditions, we find that the currents are equally large but with opposite signs. We interprete this as correlated transport of electrons in one array, and holes in the other array. The experimental results show qualitative agreement with numerical simulations.
