Static RAM created out of carbon nanotubes

We’re already at the point where the features we etch into processors are about the same size as some molecules—hemoglobin, for example, is five nanometers across. Too much smaller, and the behavior of electrons will become dominated by quantum effects, potentially causing some unpredictable behavior. One potential solution to this is to actually use individual molecules to create the features on chips. Carbon nanotubes are promising candidates, as they naturally come in both semiconducting and metallic forms. But getting the right kind of nanotubes into a structure where they perform consistently has been a challenge. Now, a team has shown that the properties of nanotubes can be manipulated and preserved in a way that could make them useful for electronics. While the work was done with populations of nanotubes rather than single molecules, it did manage to turn the nanotubes into functional RAM. Read 8 remaining paragraphs | Comments
