The transition from single-layer to bilayer growth of molybdenum disulfide on the Au(111) surface is investigated by in situ low-energy electron and photoemission microscopy. By mapping the film morphology with nanometer resolution, we show that a MoS2 bilayer forms at the boundaries of single-layer single-domain MoS2 islands and next to merging islands whereas bilayer nucleation at the island centers is found to be suppressed, which may be related to the usage of dimethyl disulfide as sulfur precursor in the growth process. This approach, which may open up the possibility of growing continuous films over large areas while delaying bilayer formation, is likely transferable to other transition metal dichalcogenide model systems.

This paper reports the enhancement of the electrochromic properties in the infrared, IR, region of radio frequency sputtered WO3 thin films thanks to a careful optimization of the deposition conditions. From the combination of various techniques of characterization, the optical performances, in particular, the contrast in reflectance between the inserted state and the deinserted one, upon cycling in H3PO4 liquid electrolyte, are correlated to the film morphology and composition. Films, grown in higher chamber pressure, exhibiting a lower density and a O/W ratio higher than 3, show the most promising behavior. Finally, first trends on the incorporation of the WO3 single layer in full electrochromic devices are discussed.
