Researchers Develop World’s First Non-Silicon 2D Computer | Sci.News

Key takeaways:

Penn State researchers have built the first computer entirely from 2D materials, using molybdenum disulfide (MoS₂) for n-type transistors and tungsten diselenide (WSe₂) for p-type transistors—replacing traditional silicon.
The team created a functional CMOS (complementary metal-oxide semiconductor) computer capable of performing basic logic operations using over 2,000 2D transistors.
Large sheets of 2D materials were fabricated using metal-organic chemical vapor deposition (MOCVD), and careful tuning allowed proper control over transistor threshold voltages.
This one instruction set computer operates at low voltages and minimal power, with logic functions running at up to 25 kilohertz suitable for basic processing tasks.
While performance lags behind current silicon chips, this marks a breakthrough in post-silicon computing, offering a potential path forward for future ultra-thin and energy-efficient electronics.
