1. Isolated flakes: Monolayer, single-crystalline WSe2 flakes are epitaxial deposited on sapphire substrate. The flakes are distributed across the whole surface of sapphire. Sizes of the flakes are about 50~150 micrometers. 

2. Monolayer continous film: Monolayer and continuous WSe2 film is epitaxial deposited on sapphire substrate. WSe2 film covers the full area and the monolayer ratio is over 95%. 

3. Multilayer continous film.
