Graphene nanoribbons could be the savior of Moore’s Law



Work on nanoribbons over the past decade has revolved around using lasers to carefully sculpt ribbons 10 or 20 atoms wide from larger sheets of graphene. On the scale of billionths of an inch, that probably sounds incredibly precise. However, even a few carbon atoms can — one way or the other – completely alter the properties of the ribbon, preventing it from working as a semiconductor at room temperature.


Fischer begins by synthesizing rings of carbon atoms similar in structure to benzene. Heating these molecules under the right conditions encourages them to bind together in a long chain. A second heating step strips away most of the hydrogen atoms, freeing up the carbon to form bonds in a honeycomb-like structure — graphene. This process allows Fischer and his colleagues to control where each atom of carbon goes in the final nanoribbon.Read The Rest: www.extremetech.com/extreme/176676-graphene-nanoribbons-could-be-the-savior-of-moores-law/

  1. It's been around for a while now. I'm not holding my breath. I always suspect, when they advertise these things as they do, they are just trying to drum up support for research funding, not much of it will go into this. The solid stuff is kept under lock and key. Look at it this way... if there was real potential for economic movement? Why would you not keep that in your pocket? If I had a gold mine, literally or figuratively, I wouldn't just advertise it's location and see if someone else could find more of the gold than I could... innit?
