Crafting Suspended Graphene Sheets Over Superconducting Aluminum Electrodes for Next-Generation Nanoelectronics

This research presents a pioneering technique for fabricating suspended graphene sheets over superconducting aluminum electrodes, optimized for advanced mechanical and electronic applications. By employing precise nanofabrication methods and tailored environmental conditions, we achieve stable, defect-free graphene suspensions with seamless integration onto aluminum electrodes. These structures demonstrate enhanced superconducting proximity effects and exceptional mechanical resilience, enabling superior performance in nanoelectromechanical systems (NEMS) and quantum devices. The combination of suspended graphene with superconducting electrodes offers a versatile platform for exploring quantum transport phenomena and developing ultrasensitive detectors. Our scalable and reproducible approach paves the way for innovative applications in quantum computing, high-precision sensing, and hybrid 2D material systems.
