摘要：
We report on the successful fabrication and electrical transport properties of single quantum wires fabricated by using InAs/AlGaSb heterostructures. Magnetotransport and high electric field characteristics have been measured on the various size of quantum wires. From comparison with the channel length-dependence of I-V characteristics of the differ ent size quantum wires, we try to develop a comprehensive understanding on the quasi-one dimensional electron transport in InAs from the nearly ballistic regime to the hot electron condition. The fabrication and characteristics of superconducting weak link InAs/Pb:In devices are also reported. The modulation of differential conductivity has been observed by the gate bias voltage between the superconducting Pb-In contacts. (C) 1997 Academic Press Limited
