2D WSe2 films synthesized by thermally assisted conversion method

In this paper we report on the synthesis details of WSe2 nanolayers by thermally assisted selenization method of pre-deposited tungsten films in Chemical Vapour Deposition (CVD) reactor. Optical microscopy reveals WSe2 domains uniformly distributed with predominantly triangular shapes. Raman spectroscopy as well as UV-VIS-NIR spectrophotometry and sheet resistance measurements are used for characterization of the obtained 2D WSe2.
