Description
Van der walls flakes (powdered crystals) of WSe2 have been synthesized through high-pressure reaction at elevated temperatures. Each powdered domain consists of vdW layered WSe2 sheets. These individual WSe2 crystallizes measure somewhere from 100nm to 10 of um in size. vdW powders are ideal for liquid phase exfoliation, thin-film deposition, catalysis, and some electronics (detectors and sensors) work.
