United KingdomThe article discusses the challenges and advancements in fabricating high-performance, energy-efficient transistors using two-dimensional (2D) materials, particularly focusing on the limitations of scaling down transistor components. As traditional silicon-based transistors approach physical limits, researchers are exploring alternatives like 2D materials for continued miniaturization. The critical factors include reducing both channel and contact sizes, with significant emphasis on overcoming contact resistance issues. While prior studies have explored channel scaling, metal contact scaling remains under-researched. Researchers have attempted to improve contact performance through material modifications and interface engineering, but achieving sub-20-nm contacts remains technically challenging. A key factor in determining contact performance is the transfer length (LT), which represents the effective current injection region between metal contacts and 2D materials. Previous studies suggest that LT varies based on interface properties and material characteristics, complicating experimental validation. Some experiments have estimated LT values ranging from 13 nm to 35 nm, indicating
