Abstract

Quantum point contacts with a short (100-nm) channel in a high-mobility two-dimensional electron gas of GaAs/Al(Ga)As heterostructures and a short-channel p-type field-effect transistor in a silicon-on-insulator structure were fabricated and studied experimentally and by modeling at the Rzhanov Institute of Semiconductor Physics, Siberian Branch, Russian Academy of Sciences, Novosibirsk, Russia, in order to study the response of the samples to weak irradiation by an electromagnetic field with a frequency of ~2 GHz. This response in the tunneling mode at a temperature of 4.2 K turned out to be giant and was observed against the background of features caused by impurity disorder.

量子点接触和硅场效应晶体管的微波光电导特性

俄罗斯新西伯利亚俄罗斯科学院西伯利亚分院 Rzhanov 半导体物理研究所制作了在 GaAs/Al(Ga)As 异质结构的高迁移率二维电子气中具有短（100 纳米）沟道的量子点接触以及硅绝缘体结构中的短沟道 p 型场效应晶体管，并对其进行了实验和建模研究，以研究样品对频率约为 2 千兆赫的电磁场微弱辐照的响应。在 4.2 K 的温度下，这种隧道模式的响应是巨大的，是在杂质无序造成的特征背景下观察到的。
