Abstract
An embodiment relates to a method for controlling the surface characteristics and thickness of a multilayer transition metal dichalcogenide thin film. By forming an amorphous transition metal oxide thin film on a multilayer transition metal dichalcogenide thin film, and then treating the multilayer transition metal dichalcogenide thin film having the amorphous transition metal oxide thin film formed thereon with an aqueous solution of ammonium sulfide at least once, the surface characteristics and thickness of the transition metal dichalcogenide can be controlled in a simple and low-cost manner without complex equipment settings for heat treatment, plasma and laser etching, and so on.
