Growth of 2D materials by Chemical Vapour Deposition

(or variants thereof)

Among the TMD family, WSe2 is the first 2D material grown at C2N, with a focus on mono-layer control  and crystal quality. The growth is performed in a CVD oven, using W and Se solid precursors.

Characterisation tools such as Raman and Photoluminescence spectroscopy are used to assess the material quality, which are readily available. Further characterisations (electrical, ARPES, TEM, XRD) can be performed within the Material Dpt of C2N.
