Carbon could replace silicon in next-gen transistors

US engineers have developed a technique that replaces silicon with carbon to make next-generation semiconductors. Boffins at Princeton University said that the electronics industry has pushed the capabilities of silicon - the material at the heart of all computer chips - to its limit, and that carbon could offer a viable replacement.

Stephen Chou, professor of electrical engineering at Princeton, explained that graphene, a single layer of carbon atoms arranged in a honeycomb lattice, could allow electronics to process information and produce radio transmissions 10 times more efficiently than silicon-based devices

So carbon will replace silicon in computer chips, silicon will replace carbon in lithium ion batteries, batteries in upcoming gadgets will be replaced by fuel cells, and fuel in cars will be replaced by batteries.

The problem is, carbon based parts become very conductive when they experience thermal decomposition. Basically, heat causes the molecules to break down (through pyrolysis) and then they become conductive. Carbon by itself is a very conductive non-metal. This may or may not be a good idea... but silicon is a safe element to use in this regard. A lot of electrical fires are caused by PCB material thermally decomposing to carbon, creating conductive paths that then generate more heat and eventually lead into an open fire.

I think I read something quite a while back about carbon fibers being used in lue of fiber optic cable to carry data, massively incresing the amount of data thruput. I think that the introduction of carbon fiber and arranged carbon molecules could be a big leap in miniturization. I cant waot to see what will change in the coming future as these kinds of advances are investigated!

They can't do that! If they replace the silicon with carbon, won't that INCREASE greenhouse gasses?
And what about their carbon footprint? Oh noooooooooooooooooooooooooooooooo

I thought that Intel already switched to using Hafnium dioxide instead of silicon dioxide for its latest CPUs... and that this process is already 10x more efficient than silicon...

Yes, they have. But, it's hafnium dioxide grown on a silicon substrate. The transistor is still made of silicon, it just uses a different material as the gate dielectric. Many transistors in many application use various materials other than silicon dioxide for the gate dielectric.

By using the new high k-dielectric (Which may or may not be Hafnium Dioxide. It's some hafnium compound, though. They haven't said what it is.), they're able to make the gate oxide layer twice as thick, which seriously reduces the ability of electrons to quantum magically skip across it as if it wasn't there, reducing power consumption dramatically while offering the same performance of the transistor.

I seem to remember reading about using diamond lattices as a means to store data a while ago and diamonds are made of carbon. Talk about a non-volatile storage medium...
