World’s Smallest Transistor Is Cool But Won’t Save Moore’s Law

Researchers have created a 1-nanometer transistor gate, and while some believe this may salvage Moore’s Law to some extent, MIT thinks that'd just be wishful thinking because it’d be really difficult to put billions of transistors on a single chip.

آ…the researchers explain that the device has been built using carbon nanotubes and molybdenum disulfide, creating a transistor with a gate length of just one nanometer. It’s an impressive achievement, andآ—in theory, at leastآ—it means that it would be possible to squeeze far more of the small switches into a chip than could ever be achieved with silicon. For some context, the current state-of-the-art chips use transistors with a 14-nanometer gate, and 10-nanometer chips are on the way. The result is, however, just a proof of conceptآ—a long way from a viable product. Turning these nanotube transistors into a processor would require billions of the switches to be reliably created on a single chip. That may be possible, but it could also be cripplingly expensive.
