| Popis: | 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. |
