摘要

本研究介绍了一种无催化剂生长的单根氮化铝纳米线场效应晶体管（AlNNW-FET）的电传输特性，该晶体管具有 26.9 pS 的超高跨导、795.9 的高导通/关断电流比、9.8 x 10-4 Ω-1.cm-1 的高电导率以及 10 pA 的超低漏电流。AlN 纳米线的电导率比已报道的研究高出两个数量级。AlNNW-FET 显示出主要的 p 型导电性。这种 p 型导电性可归因于铝空位以及由铝空位和氧杂质组成的复合物。因此，所制备的 AlNNW-FET 具有高性能、高性价比和高功率效率的特点，非常适合用于低功耗、高温的纳米电子和压电传感器应用，以及包括光机电器件和热释电光电探测器在内的集成光电器件。

High-Transconductance and Low-Leakage Current Single Aluminum Nitride Nanowire Field Effect Transistor

This study presents electrical transport properties of a catalyst-free grown single aluminum nitride nanowire field effect transistor (AlNNW-FET) exhibiting a very high transconductance of 26.9 pS, high on/off current ratio of 795.9, high conductivity of 9.8 x 10-4 Ω-1.cm-1, and a very low leakage current of 10 pA. The conductivity of AlN nanowire is two orders of magnitude higher than the reported studies. The AlNNW-FET reveals a dominant p-type conductivity. The p-type conductivity can be attributed to aluminum vacancies and complexes composed of Al vacancies and oxygen impurities. In consequence, the fabricated AlNNW-FET with high-performance, cost-effectiveness, and high-power efficiency is very well suited for use in low power and high temperature nanoelectronic and piezoelectric sensor applications, as well as integrated electro-optical devices including optomechanical devices and pyroelectric photodetectors.
