Two-Dimensional Versions of High-K Materials Offer New Future for Chips

Thinning high-K materials down to two dimensions offers the same band gap as a silicon transistor but ten times smallerGraphic Illustration: Science Advances

Silicon has been the mainstay of chips for much of their history (a history you can explore in IEEE Spectrum’s Chip Hall of Fame). This is in large part because silicon possesses a “Goldilocks” band gap of 1.1 electron Volts (eV), which makes it possible to operate integrated circuits at a low voltage, leading to reduced...
