Graphene as a replacement for Silicon?

[mi1ez]

Interesting article on the BBC website this morning:

i've heard of this before..... but its not really going to acheive much in the near future (by the time it exists, AMD will be dead and intel will just use whats cheap and charge us $90000000000 for it)

 

[dobby]

Nah, if AMD go out, i grantee that Big Blue, IBM, will take it place, the reason they arnt right now, is becasue a third party in the CPU market is just to riscky. but if IBM started making CPU they would do soemthing inavitive.

this graphene sounds interesting, but its gonna be a while.

its a shame BBC dont get very technical. as far as im aware 45Nm trans are 4 atoms thick.

thanks for Linking this miles

I'm intrigued whether it'll be this or the optical circuits on Tom's the other day!
Or one then the other.

They already fried cancerous cells in mice with nanotech last week... its very promising indeed...graphene is mechanical tough, flexible, transparent, and a great conductor...and electrons can travel upto more than 100 times faster in graphene coampared to silicon ..yippikaiyee

 

[dobby]

might replace cooper internet wires, Might being key, i think its more likely to go optical.

amdfangirl I have 1.5 / 384 here ... out in the boonies south of Perth (end of the Freeway).

We are connected to poor copper here (with archaic gear in the exchanges) ... no fibre to the street like Sydney.

Sometimes I have to hit the router to scare the electrons to go a bit faster.

I have poor eyesight so I can't go optical

lol ...

how strong would a "cable" of graphene actually be? because if it get snapped in two when you flick it, it wouldn't do well as a LAN cable or internet cable at my home....

 

[Reynod]

Wouldn't it be more like two cables ??

Superposition ...

 

[dobby]

lol, no it would be in a twisted pair, to wire in 1 cable (or more sets of 2)

yes it would be using suposition and the like

 

[Reynod]

I wonder if coating / bonding conventional cable with graphene might be something?

 

[Reynod]

It isn't.

The LCD monitor idea in the article looks promising ... at least sounds like it can be practical soon.

LCD screens need a lot of work.

I tuned a new 42" Panasonic Vienna Plasma today ... picture was astounding compared to the LCD I was watching earlier ... just so much brighter and the Contrast ratio was uber.

Technology to improve LCD screens will be welcome ... particularly given the Plasma's don't last as long ... ( i it 5 years or so ??).
