Centimeter-Scale MoS2 on Solid Electrolyte Substrate by Sulfurization of Molybdenum Thin Film

Solid-state electrolytes have attracted significant attention in rechargeable battery and solid-state device research due to the added benefits over the liquid electrolytic counterpart owing to their solid nature. Here, we demonstrated centimeter-scale growth of MoS2 thin film, a promising two-dimensional (2D) material for transistor and energy storage, on Li-ion solid electrolyte substrate by sulfurization of Molybdenum thin film. The sulfurized film was characterized using a combination of spectroscopic and microscopic analyses, including optical microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and Raman spectroscopy. The film was further characterized by electrical probing to measure the film quality and underlying transport mechanism.
