Carbon nanotube computer

Carbon nanotube computer refers to a computer built entirely using carbon nanotubes (CNT) based transistors.[1][2] Researchers from Stanford University said that they had successfully built a carbon nanotube computer and their research paper published on 25 September 2013 in the journal Nature.[3] They named their first carbon nanotube computer Cedric.[4] It has a one-bit processor containing just 178 transistors.[5]

In 2019, a team at the Massachusetts Institute of Technology created the 16-bit processor called RV16X-NANO. With 14 000 transistors (compared to only hundreds in the first CNT computer made in 2013) it is the largest computer chip yet to be made from carbon nanotubes. It was able to execute a "Hello, World!" program with a message: “Hello, world! I am RV16XNano, made from CNTs”.[6] It is based on the RISC-V instruction set and runs standard 32-bit instructions on 16-bit data and addresses.[7][8]
