A. Pfund, I. Shorubalko, R. Leturcq, K. Ensslin

摘要:

我们测量了有限偏压下通过InAs纳米线中顶栅形成的双量子点的输运。泡利自旋波卡德被证实与几个电子在点。这是预期的,因为InAs中的小交换相互作用和大的单重态-三重态分裂,这可以通过栅极电压来测量和调节。

英文摘要:

We measure transport at finite bias through a double quantum dot formed by top-gates in an InAs nanowire. Pauli spin-bockade is confirmed with several electrons in the dot. This is expected due to the small exchange interactions in InAs and the large singlet-triplet splitting, which can be measured and tuned by a gate voltage.
