Growth of Tellurium Nanobelts on h-BN for p-type Transistors with Ultrahigh Hole Mobility

Nano-Micro Letters, Год журнала: 2022, Номер 14(1)

Опубликована: Апрель 19, 2022

Abstract The lack of stable p -type van der Waals (vdW) semiconductors with high hole mobility severely impedes the step low-dimensional materials entering industrial circle. Although black phosphorus (bP) and tellurium (Te) have shown promising mobilities, instability under ambient conditions bP relatively low Te remain as daunting issues. Here we report growth high-quality nanobelts on atomically flat hexagonal boron nitride (h-BN) for high-performance field-effect transistors (FETs). Importantly, Te-based FET exhibits an ultrahigh up to 1370 cm 2 V −1 s at room temperature, that may lay foundation future 2D metal–oxide–semiconductor (p-MOS) inverter. vdW h-BN dielectric substrate not only provides ultra-flat surface without dangling bonds nanobelts, but also reduces scattering centers interface between channel material layer, thus resulting in "Image missing".
