| Abstract | |
The plethora of new transition metal dichalcogenides (TMDs) materials have attracted a major attention during the last years due to a diversity of new possibilities of applications in different areas from electronic and photonic devices to new sensors and catalysts, as well as a large playground of 2D materials to explore new physical phenomena. Many efforts have been done to develop new growth techniques that can produce single-layer TMDs in large areas and with high quality (low density of defects). Another important issue for electronic device integration is how to perform electrical contacts that show a metallic behavior instead semiconductor junctions. In this work, we have systematically studied the epitaxial growth of MoS2 on Ag(111) using the physical vapor deposition method (PVD). The results, based on a multiple technique approach, demonstrate that is possible to produce a single-layer 1H -MoS2 film on Ag(111). The material presents a metallic behavior due to an electronic hybridization between the MoS2 states and the Ag(111) states as results of the strong TMD-substrate interaction at the interface. This metallic character is preserved even after exposure to atmosphere and hostile oxidation environment which indicates that silver is probably an excellent candidate to perform metal contacts on sulfur-based TMDs.
