IBM Creates Ring Oscillator on a Single Nanotube 159
deeptrace writes "IBM has combined CMOS circuitry and a single carbon nanotube to implement a 5 stage ring oscillator. Even though the oscillator runs at just 52 MHz, they expect that it could reach the GHz range with improvements. The frequency of the current oscillator was higher than previous circuits using multiple nanotubes. IBM describes the achievement in the paper "Integrated Logic Circuit Assembled on a Single Carbon Nanotube" to be published this week in the journal Science."

Which is why communism fails. If everyone's the same regardless, there's no incentive to innovate. But that's aside the point.
Patents aren't evil, in fact there's nothing wrong with them. It's copyrights that are abused. A patent is to protect your work. A copyright is to extort as much money as possible from something that serves absolutely no tangible purpose. But rest assured, it will be patented. My dad co-holds a patent that's used in the process of wafer processing, and it's in fact an extremely simple concept (of course, considering the fact that by age twelve I came up with a solution that increased the accuracy of their heating uniformity data, which was another extremely simple concept, I'd really have to wonder how smart most of the engineers are). Other manufacturers, to my understanding, can pay to license the idea and use the technology- it's not being reserved exclusively for the patent-holder.

I believe one of the big problems is the replication that you're speaking of. From my understanding they don't really have a great idea of how to mass produce predictably shaped nanotubes yet. http://www.newscientist.com/article.ns?id=dn8888 [newscientist.com] has a little bit of info on this too.
