Northwestern University engineers say that have finally found the key to practical use of carbon nanotubes (CNTs) in integrated circuits. Individual transistors made from CNTs are faster and more energy-efficient and reliable than those made from other materials.
The problem. But making the leap to wafer-scale integrated circuits (a microprocessor typically has a billion transistors) is a challenge. The process is incredibly expensive, often requiring billion-dollar cleanrooms to… read more
