Writing in Nature, Ghosh et al. 3 and Ao et al. 4 present the first computer processors made from thousands of atomically thin 2D transistors integrated onto single chips.
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.
“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 ...
2D material is a fairly new research field—only a little over 5 years old—that holds a lot of promise. Everyday, scientists continue to discover new types of 2D materials such as graphene ...
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 ...
To make the computer, the researchers used two different 2D materials: molybdenum disulfide for one type of transistor and tungsten diselenide for another. Image: Conceptual illustration of a ...
“This marks the first time a computer has been built entirely from 2D semiconductors,” said Dr. Saptarshi Das, a professor of engineering at Penn State and the project’s lead.
