In this talk, I will elucidate on a recently discovered, unprecedented, substrate assisted, anomalous corrosion or self-limiting electrochemical ablation (EA) process that transforms bulk layers of various two- dimensional (2D) transition metal dichalcogenides (TMDCs) into their corresponding monolayers quickly and at room temperature when subjected to a high anodic potential. In particular I will explain what role does the substrate, pH, electrolyte solution, applied anodic potential, temperature and finally, in specific cases, self-assemble monolayers (SAMs) play in determining the corrosion rates for the bulk and monolayer which ultimately leads to successful conversion of multilayer TMDCs into their corresponding monolayer. I will also talk about thin film transistors (TFTs) based on these monolayers which demonstrate current ON-OFF ratios in excess of 10⁷ along with ON currents in the range of ~100µA/µm which is on-par with any state-of-the-art TFT technology.
