description

A team of engineers from Stanford University have built a basic computer using carbon nanotubes, a semiconductor material that has the potential to launch a new generation of electronic devices that run faster and use less energy. The unprecedented research has been featured in the journal Nature and was led by Stanford professors Subhasish Mitra and H.-S. Philip Wong. “People have been talking about a new era of carbon nanotube electronics moving beyond silicon,” said Mitra, an electrical engineer and computer scientist. “But there have been few demonstrations of complete digital systems using this exciting technology. Here is the proof.” Carbon nanotubes Carbon nanotubes (CNTs) were first used to make transistors, the on-off switches at the hard of digital electronic systems around 15 years ago. However, imperfections in the material have long frustrated efforts to build complex circuits using CNTs. CNTs are long chains of carbon atoms that are extremely efficient at conducting and controlling electricity. They are so thin – thousands of CNTs could fit side by side in a human hair – that it takes very little energy to switch them off, according to Wong, a co-author of the paper. “Think of it as stepping on a garden hose,” Wong said. “The thinner the hose, the easier it is to shut off the flow.” Electronic transistors In theory, this combination of efficient conductivity and low-power switching make carbon nanotubes excellent candidates to serve as electronic transistors. “CNTs could take us at least an order of magnitude in performance beyond where you can project silicon could take us,” Wong said. As part of the study, the CNT computer designed by the Stanford researchers performed tasks such as counting and number sorting. It runs a basic operating system that allows it to swap between these processes. In a demonstration of its potential, the researchers also showed that the CNT computer could run MIPS, a commercial instruction set developed in the early 1980s by then Stanford engineering professor and now university President John Hennessy.

Carbon nanotubes (CNTs) were first used to make transistors, the on-off switches at the hard of digital electronic systems around 15 years ago. However, imperfections in the material have long frustrated efforts to build complex circuits using CNTs.

CNTs are long chains of carbon atoms that are extremely efficient at conducting and controlling electricity. They are so thin – thousands of CNTs could fit side by side in a human hair – that it takes very little energy to switch them off, according to Wong, a co-author of the paper.

“Think of it as stepping on a garden hose,” Wong said. “The thinner the hose, the easier it is to shut off the flow.”

In theory, this combination of efficient conductivity and low-power switching make carbon nanotubes excellent candidates to serve as electronic transistors.

“CNTs could take us at least an order of magnitude in performance beyond where you can project silicon could take us,” Wong said.
