Driven by the demand for high integration and ultralow power consumption, next-generation integrated circuits  is advancing to the molecular and atomic scale. Our research focuses on molecular graphene nanoribbons (GNRs) as the core material platform. We tackle existing bottlenecks via targeted innovations in contact engineering, gate design, encapsulation and scalable integration. These efforts will upgrade GNRs from single-transistor prototypes to multifunctional integrated circuits, laying the groundwork for next-generation atomic-scale electronics.
