| Abstract Scope |
The synthesis of high-quality transition metal dichalcogenides films is of significant interest for potential applications in nanoelectronic and thermoelectric devices. Molecular beam epitaxy is a promising route towards this aim providing fine control over growth conditions. To further the present understanding of processing methods on the quality of transition metal dichalcogenide thin films, we study the effect of using a ripening step in the early stages of WSe2 thin film growth. We use a combination of in-situ low energy electron diffraction and reflective high energy electron diffraction along with ex-situ atomic force microscopy to comment on differences in growth mode and crystallinity. In-situ x-ray photoemission will also be employed to comment on differences in the chemical properties of the grown thin films. |
