Beyond Silicon: Penn State Creates CMOS Computer from 2D Materials
2025-06-14
Researchers at Penn State have achieved a breakthrough, creating a functional CMOS computer using two-dimensional (2D) materials—just one atom thick—instead of silicon. Published in Nature, this development represents a significant leap towards thinner, faster, and more energy-efficient electronics. Using molybdenum disulfide and tungsten diselenide for n-type and p-type transistors respectively, the team overcame previous challenges in scaling 2D materials to complex computer architectures. While the operating frequency is currently low, this research paves the way for moving beyond silicon-based technology, promising a new era in electronics.
