Transistors are the most fundamental building blocks of modern electronic devices. They perform various functions that range from logic operations to voltage regulations. Since their creation, researchers in the field have devoted significant effort to shrinking down the size of transistors, as transistor scaling provides many desirable benefits, including cost reduction and higher computational power per chip. However, the minimum feature size of modern transistors is already in the nano-scale range, and we are approaching a scaling limit that cannot be overcome with conventional transistor designs. Exploratory research is needed to develop new materials systems that can replace silicon, the most widely used material in transistors. Theoretical studies have shown that transition metal dichalcogenides (TMDCs) could be promising candidates for next generation electronics, and Louis aims to demonstrate their electronic applications experimentally.
