Graphene CPU

RF properties of upto 500ghz. They are focussing on different substances like carbon nanotubes for computer processors as graphene does not seem viable from what I read and I read all of it. I read it with an excited and interested gaze though!
 
That's a very old article now.

Problems with graphene are being solved all the time, but there are so many steps to creating chips it will be years before it will hit the market.

What they are looking at for 7nm (~2020) is Indium-Gallium-Arsenide. It gets very foggy after that but I would not expect any major materials change until the next decade sometime.
 
I am reading a book called Physics of the future, by Michio Kaku where he looks at near and far future application of technology.

He states Moores law will end in about 20 years or so, where 5nm chips will actually be too small for electrons to pass through the processor and it will enter into the Heisenberg uncertainty principle (you cannot know both the location and velocity of a particle at the same time)

This will mean although graphene will allow processors to be fast they will never be able to get smaller than this amount, they must be more efficient.

The speed of electron transfer is roughly 1/100th the speed of light (180,000 miles/s) this will increase with graphene but still the size of the 5nm will never be broken unless quantum computing actually comes about soon.
 
I'm not a fan of Kaku, I think he dumbs things down way too much and sets himself up as an expert in fields he has no knowledge of.

Moore's Law is dead already, but all it ever was was an observation, Kaku obsesses over it too much.

Optical interconnects & photonics will eventually replace copper/electrons.

I am writing a book about the evolution of robotic kind using cloud computing to power processors, basically using any free runtimes of processors in anything from phones to super compouters to run the hive.

I wrote a whole chapter on light based computing and then scrapped it as it was way too technical for an average reader.

I think Kaku does a good job of giving info to the masses, he isn't as flambouyant as Degrasse-tyson or as engimatic as Cox but he does a good job in the 3 books of his I have read, Visions, Parallel Universes and Physics of the future.

If you want some real high brow science learning check out sixtysymbols on youtube. I often have to go off and wiki for days afterwards....

Edit: It was the fact that he was stating that the processing power will taper off the close we get to 5nm not that 18mont/cpu power doubles rule, that has been sdmashed a while ago, but the fact that we cannot get to 5nm and that 10 years ago the crowd he was lecturing would have laughed at him but now they are looking to combat this before it becomes a problem. The point was how the processor industry becomes huge business and if it fails the economy will fail.

I don't think that info is accurate.

1. Moores Law ended in 2012. Still stuck at 22nm and 28nm.
2. I read circuits can be shrunk to 1nm ages ago. Apparently quantum tunnelling isn't as bad as was predicted. The problem is fabrication.
3. Electronic signals move at lightspeed. If I remember the actual speed of electrons in a conductor is very slow. Far slower than 0.01c. On the order of centimetres per second.

0.2cm/s apparently, but they are shunted like a train.

Here's a page I read recently about gold vs silver vs copper. How does the idea of silver traces sound? :D

As far as graphene, transistors have been demonstrated near the THz range, progress is steady but it's a long haul. Here is an example of a milestone story:

Speed of light = c ONLY through a vacuum btw.

I am using figures quoted on the internet and from the book, but I might be wrong.

This latest book was written in 2011 and he was giving lectures to Microsoft on Moores law, so I think it still applies. Being stuck on 22nm hasnt stopped the addition of more cores some how. Silcon's days are numbered totally
