“Moore’s Law is morphing into something that is about new materials,” said Alex Lidow, a semiconductor industry veteran and CEO of Efficient Power Conversion (EPC). EPC is making a possible silicon replacement, gallium nitride (GAN), which is a better conductor of electrons, giving it performance and power-efficiency advantages over silicon, Lidow said. GAN is already being used for power conversion and wireless communications, and could make its way to digital chips someday. “For the first time in 60 years there are valid candidates where it’s about superior material rather than smaller feature size,” Lidow said.
