Resumé

Sub-10 nm continuous metal films are promising candidates for flexible and transparent nanophotonics and optoelectronic applications. In this article, it is demonstrated that monolayer MoS 2 is a perspective adhesion layer for the deposition of continuous conductive gold films with a thickness of only 3–4 nm. Optical properties of continuous ultrathin gold films deposited on 2D MoS 2 grown by chemical vapor deposition are investigated by spectroscopic ellipsometry over a wide wavelength range (300–3300 nm). Results show that optical losses in ultrathin films increase with decreasing thickness due to the fine-grained structure and the presence of a small number of voids, however, they exhibit metallic properties down to a thickness of 3–4 nm. The atomic-scale MoS 2 interfaces can be transferred to any substrate and thus open up new opportunities for the creation of metasurfaces and a new type of van der Waals heterostructures with atomically thin metal layers.
