Computer processors built from 2D materials These prototype processors made from atomically thin materials offer a glimpse into a post-silicon-transistor future, but scaling challenges remain.

In a world first, they used two-dimensional (2D) materials, which are only an atom thick and retain their properties at that scale, unlike silicon, to develop a computer capable of simple operations.

Built at a nanofabrication unit at The Pennsylvania State University in the US, the research team has demonstrated the successful working of the world's first CMOS computer made using two ...

“Our 2D CMOS computer operates at low-supply voltages with minimal power consumption and can perform simple logic operations at frequencies up to 25 kilohertz,” said first author Subir Ghosh ...
