This experimental study investigates a novel multi-functional one dimensional-two dimensional (1D-2D) heterojunction made of two different band-gap semiconductors, i.e. single-walled carbon nanotube (SWCNT) and tungsten di-selenide (WSe₂). The proposed ultra-scaled van der Waals junction behaves like a ${p}$ -type field-effect transistor (FET) or a gated ${p}$ - ${n}$ diode, depending upon the gate bias. A detailed physical study of charge transportation mechanism is presented in a wide range of applied potentials. The obtained results are important towards scaling nanoelectronics to atomic thicknesses by means of the 1D-2D hybrid junctions with additional multi-functional solid-state devices.

混合维一维-二维范德华单壁碳纳米管-WSe2异质结的实验研究

本实验研究调查了由两种不同带隙半导体，即单壁碳纳米管 (SWCNT) 和二硒化钨 (WSe ₂ )制成的新型多功能一维-二维 (1D-2D) 异质结。提议的超尺度范德瓦尔斯结表现得像一个 ${p}$ 型场效应晶体管 (FET) 或门控 ${p}$ —— ${n}$ 二极管，取决于栅极偏置。在广泛的应用电位下，对电荷传输机制进行了详细的物理研究。获得的结果对于通过具有附加多功能固态器件的 1D-2D 混合结将纳米电子器件缩放到原子厚度非常重要。
