Hydrogen-assisted growth of one-dimensional tellurium nanoribbons with unprecedented high mobility

1D nanoribbons (NRs) derived from 2D materials have attracted substantial research interest recently. Here, quasi-1D Te NRs have been controllably synthesized by CVD, and the corresponding growth mechanism suggests that hydrogen and confined space govern the morphology of 1D Te. The quasi-1D Te NRs-based field-effect transistors exhibit ambipolar features and achieve record-set mobility metrics.
