In a bold challenge to silicon s long-held dominance in electronics, Penn State researchers have built the world s first working CMOS computer entirely from atom-thin 2D materials. Using molybdenum disulfide and tungsten diselenide, they fabricated over 2,000 transistors capable of executing logic operations on a computer free of traditional silicon. While still in early stages, this breakthrough hints at an exciting future of slimmer, faster, and dramatically more energy-efficient electronics powered by materials just one atom thick.
