Title: Synthesis, characterization and electrostatic properties of WS{sub 2} nanostructures

Abstract

We report the direct growth of atomically thin WS{sub 2} nanoplates and nanofilms on the SiO{sub 2}/Si (300 nm) substrate by vapor phase deposition method without any catalyst. The WS{sub 2} nanostructures were systematically characterized by optical microscopy, scanning electron microscopy, Raman microscopy and atomic force microscopy. We found that growth time and growth temperature play important roles in the morphology of WS{sub 2} nanostructures. Moreover, by using Kelvin probe force microscopy, we found that the WS{sub 2} nanoplates exhibit uniform surface and charge distributions less than 10 mV fluctuations. Our results may apply to the study of other transition metal dichalcogenides by vapor phase deposition method.
