First steps of commercial Carbon nanotube

[Olikan]

For the first time, more than ten thousand working transistors made of nano-sized tubes of carbon have been precisely placed and tested in a single chip using standard semiconductor processes.

oh my, these comments are spectacular

"Great, but will hardware enthusiasts still be able to build computers with these processors? Miniaturizing worries me for that very reason."

"Sure they will. We will probably just need a scanning electron microscope and a really fine pair of needle-nose pliers."

This is very exciting :thumbsup: The silicon transistor will be to my children as the vacuum tube was to me, history.

Who gets this tech?

I mean is this why IBM silently slipped away from being a giant to a services specialized computing company?


They saw silicons end - and invested in graphene and other stuff - to be the first to mass produce it.

And thus have a node advantage ?

They will probably license the IP, like they always do...

Do you have a highend sound system . I not ready to throw my tubes away. I have nice digital system not expensive . But sound quality no where near tubes. AS for the Topic bring it sooner than later

Intel is working on this tech also . I doubt if IBM will be first out of the gate . Remeber when intel release of 45nm . IBM was Ya we have that also. YA right than 3d same thing we have that to .

My high-end sound system is already carbon-based. Vacuum tubes are inferior, was this ever in doubt?

Why would anyone be particularly excited about this? It would still take at least 10 years before this technology appears in commercial products. If at all...

Really? You can't fathom that people who are interested in device physics, materials science, etc would also be excited about the technological edge of capability in the field of computing getting another rung in the ladder of feasibility?

We have reason to be excited because news like this gives us an idea of what might be possible in the future. Everything you take for granted today was at some point in time "cutting edge" technology. Just because it isn't in your hands at this moment in time doesn't mean it doesn't matter.

My guitar amplifier uses tubes, I was always under the impression that tubes were better for creating a warm full sound. There are probably some high-end solid-state amplifiers that I never looked at due to price that are better, wouldn't doubt it.

That's fine, but do you want your CPU to run on vacuum tubes?

I think you, and Nemesis, are missing the context with which my comment was intended.

Prior to the development of transistors, vacuum (electron) tubes (or in the UK "thermionic valves" or just "valves") were the main active components in electronic equipment.

The silicon transistor replaced vacuum tubes in compute devices in the late 1950s.

Now with this history in mind, perhaps my original post carries a context that makes sense?

There are all kinds of weird things that make absolutely zero sense that people swear by in the audio industry.

Take a look at this site:

http://www.enjoythemusic.com/magazine/equipment/1103/stillpointsers.htm

Example:

At first glance, the Stillpoints look like an enlarged tip of a ballpoint pen. The ball is actually a rocket grade ceramic ball bearing, perhaps 5/8" in diameter, housed in a conical Delrin body. Peering into the ¼--20 threaded hole in the base of the cone, four other smaller ceramic balls are barely visible, suggesting a set-up similar to the hub of a bicycle, where a ring of ball bearings rides in a machined (and sometimes polished) race. But rolling a finger across the exposed ceramic ball on top reveals quite a bit of friction, indicating that the purpose of the pyramid of ceramic balls is not to dissipate energy in the fashion of various rollerblocks, but to transmit it to the four other ceramic balls within the cone. At this point, I became hopelessly baffled, and diverted my efforts to listening tests.

There was a significant improvement in clarity every time I placed a component on the Stillpoints. My jaw did not "drop", as I have experienced similar results before with the two Symposium Acoustics Rollerblocks. But "clearly", the Stillpoints are in the same league of excellence. The improvement seemed to be the equivalent of a major component upgrade, whether the Stillpoints were placed under my $300 tuner, or my $6,000 pre-amplifier. Nothing seemed immune to the beneficial effect of the Stillpoints, no matter what the priced point.

This guy has reviewed vacuum tube amps, and even diagrams for building your own.

actually only 70% of the 10000 transistors were functional the other 3000 or so were metallic nanotubes. But it's a good start, if they can get the properly functioning percentage up 5 orders of magnititude then find a way to excise any bad nanotubes from mucking up the chip these things may be good to go for something.

Agreed! :thumbsup:
70% is not bad at all considering this is still ground breaking technology.
