Wafer scale synthesis of organic semiconductor nanosheets for van der Waals heterojunction devices

Abstract Organic semiconductors (OSC) are widely used for consumer electronic products owing to their attractive properties such as flexibility and low production cost. Atomically thin transition metal dichalcogenides (TMDs) are another class of emerging materials with superior electronic and optica...
