When Intel co-founder Gordon Moore made the observation that came to be known as Moore's Law, he projected that transistor density would continue doubling in density every two years... for another ten years. Working with Tianjin University in China, though, researchers at Georgia Tech have made a breakthrough in this department by growing graphene on doped silicon carbide wafers, introducing impurities into the graphene that give it a usable band gap, enabling the researchers to create graphene transistors the size of a carbon atom. In research led by School of Physics Regents' Professor Walter De Heer, these switches can reach into the teraHertz range and run cooler than silicon transistors, potentially breathing new life into the aging Moore's Law.
