2D Transistors Take On Silicon 

Executive Briefing & Key Highlights

Atomically thin MoS₂ transistors with sub-5nm channels have demonstrated switching beyond silicon’s theoretical limits, pointing toward smaller and more energy-efficient chips for future computing. Researchers at Carnegie Mellon University have demonstrated molybdenum disulfide (MoS₂) transistors with channel lengths below 5nm that overcome a key scaling limitation of conventional silicon devices.
