Researchers have built a primitive microprocessor out of a two-dimensional material similar to graphene, the flexible conductive wonder material that some believe will revolutionize the design and manufacture of batteries, sensors and chips.

With only 115 transistors, their processor isn’t going to top any benchmark rankings, but it’s “a first step towards the development of microprocessors based on 2D semiconductors,” the researchers at Vienna University of Technology said in a paper published in the journal Nature this month.
