Growth of ultrathin MoS₂ films - Temperature dependency — •Vanessa Zeuner, Lukas Madauss, and Marika Schleberger — Universität Duisburg-Essen, Deutschland

Molybdenum disulfide (MoS₂) is an important representative of transition metal-dichalcogenides (TMDCs).With a direct bandgap it is an interesting candidate for a variety of electronic and optoelectronic applications. Therefore, the growth of large area, two dimensional films is investigated. We synthesized the MoS₂ films by chemical vapour deposition on SiO₂/Si substrates and used MoO₃ and S powders as the reactants. The influence of the temperature during the process on the morphology of the two dimensional MoS₂ flakes is studied.
