You couldn’t turn it off. And if you know anything about transistors, you know that turning on and off is sort of a transistor’s raison goddamn d’etre. So while graphene is super-fresh and all that, if it can’t turn on and off, the question of its efficacy<a target="_blank" href="http://www.maniacworld.com/question-is-moot.html" target="_blank" style="color: #007cd5; text-decoration: none; -webkit-tap-highlight-color: #ff6600">is moot</a>. But aforementioned scientists have been able to come up with an entirely different way of getting graphene to work in a transistor. The result is “a system that dramatically outperforms silicon,” says the article. “[The researchers] say the performance is ‘several orders of magnitude higher than for any reported or even projected scaled circuits.’”</p> <p style="margin: 0px 0px 1.5em; padding: 0px; border: 0px; font-size: 1.2em; vertical-align: baseline; line-height: 1.5em; color: #222222">There used to be a lot of hand-wringing that we were running up against the upper limits of <a target="_blank" href="http://en.wikipedia.org/wiki/Moore" s_law"="" target="_blank" style="color: #007cd5; text-decoration: none; -webkit-tap-highlight-color: #ff6600">Moore’s Law</a> when it came to processing power.
