Abstract

Researchers conduct a study to develop a highly scalable coating process by using the polymer-assisted deposition and apply thermolysis at a relatively low temperature without sulfurization. This process enables fine control of the precursor film, which leads to precise thickness control of the resulting molybdenum disulfide (MoS₂) film. In addition, researchers also demonstrate the fabrication of a MoS2-based photodetector with a broad spectral response and excellent performance, as indicated by its fast response time. The synthesis includes the formation of a precursor−polymer complex thin film comprising anhydrous ammonium tetrathiomolybdate (ATM) precursor and linearpoly(ethylenimine) (L-PEI).
