Abstract
2D metallic material is an important group member in 2D material family. Many applications have been applied in the catalysis and devices. In this paper, we present a novel method to prepare the tungsten 2D material, which is simple and powerful. The W thin film is deposited via magnetron sputtering. As-deposited tungsten thin film is able to be exfoliated with wet and dry methods. We show a clear layered structure of the tungsten thin film from the cross sectional view. Via the exfoliation, an large area 2D tungsten monolayer is obtained. After oxidation, the 2D material shows potentials in electric signal transport.
