Nano Size Monolayer WS2 Powder

Description

Description WS2 belongs to the family of transition metal dichalcogenides (TMDs) materials. Monolayer WS2 has been extensively studied for its unique properties that distinguish it from other 2D TMDs. Alfa Chemistry produces high quality nano-sized monolayer tungsten disulfide and is available in powder form.
