摘要
本文重点评述了无散射区电子输运在实验和理论方面的最新进展,内容涵盖半导体量子点接触的加工工艺;电导的量子化及其成因;量子点接触串、并联后,欧姆定律的遵从性;弹道输运特性的应用;以及超导量子点接触临界电流的量子化。
This paper selects to review the progress in the experimental and theoretical investigations of electronic transport in ballistic regime. The content covers the preparing technique of quantum point contacts (QPC's);the phenomenon and physics of conductance quantization; the applicability of Ohm's law in the network of QPC's;the application of ballistic transport properties; and the quantization of critical current through superconducting quantum point contacts.
