The Age of Materials
Max The Magnificent   12/3/2013 4:28:05 PM
I firmly believe that we are poised on a new "age" -- in the same way that people now refer to the past few years as the "Information Age" -- I think that the next few decades will come to be known as the "Materials Age" (see also my review on The Dissapearing Spoon)

I agree...we have largely exploited what silicon might to offer...I am amazed that although being active in this field of emerging materials I have never heard the term "stanene"!

One reason to keep on visiting EE Times to see what's hot (and what's not :-)

Such kind of conducting material if used for the interconnects will solve many a problems of heat and voltage drops especially for PCB layouts of analog circuits , in my opinion.

Since the superconducting property is available at ambient temperatures that is an added advantage over other superconductors which require sub zero temperatures to achieve the superconductivity.

I agree. Stanene is new to me but there is no question we are moving into a new age and that silicon has taken us about as far as it can. The use of monolayers of tin to reduce heat and save power within the chip is an exciting breakthrough. No surprise that so many advanced institutions are getting in on the action now.

A few qestions/ideas

This seems like a major step although the 212F deg limit seems to limit application quite a bit.  The implications of designing on a computer new materials has much larger implications though.  I had a few questions regarding application if anybody had some quick comments or ideas:

Is this believed to be easily compatible with present chip manufacturing processes?

Could this be used in other applications then just on chip - boards, wires, motors?

What would be the implications of using this for information transfer - I have little experience - with less resistence how will this affect noise in a circuit - besides just less heat/resistence?  Could it transmit dc to microwave efficiently?

There is a misspelling - Tim Valley should be Tin Valley..

I think we are good 10-20 years before fully knowing answers to your questions @chrisfolsom...this is how long I bet the technology will take to mature...BTW, I don't see 100C (212F) as a major limitation, most applications don't require it...Kris

When is a superconductor not a superconductor?

How much power can you push through it?

Is it bendable?

Can you make a bundle of them to create a not a superconductor cable?

Over what distance does it not have resistance? Article does not imply any limit, but really?

Can't wait to see these questions answered as time goes by.

As a Monty Python fan I prefer Tim Valley anyway.  Tin is toxic after all.

 

No resistance would imply no resistive heating and no scattering (meaning low noise) I think.  Also no RC delay.  Of course you have to connect it somehow to something, and then you will have resistance.  I wonder about the dielectric constant of the ribbon and how much cross talk between the two sides will be a factor.  It might not be feasible to use both sides separately, but it could give a neat way to do error checking/correction.

Thanks - 100C seems low for active circuits - if the resistance spiked while carrying current I assume it would be reclassified as a switch at best and fuse at worst.... 20 years !! I suppose I am a bit jaded, but that seems like a long time - I am also interested in this new "superconductive" insulator property - has it been used for anything yet? Can you put anything near it, or is there some dielectric effect that would create problems - does it need to be in a vacuume?
