Tunable field emission characteristics of ZnO nanowires coated with varied thickness of LANTHANUM BORIDE (cas 12008-21-8) thin films

Add time:07/24/2019    Source:sciencedirect.com

LANTHANUM BORIDE (cas 12008-21-8) (LaBx) thin films with various thicknesses were deposited on ZnO nanowire arrays by electron beam evaporation. Field emission characteristics of ZnO nanowires show close dependence on LaBx coating thickness. The turn-on field increases with increasing LaBx coating thickness from 10 nm to 50 nm. The observed phenomena were explained by a model that the tunneling at ZnO/LaBx interface dominates the emission process.
