New superconductors can be built atom by atom

Summary:
The future of electronics will be based on novel kinds of materials.
Sometimes, however, the naturally occurring topology of atoms makes it
difficult for new physical effects to be created.
To tackle this problem, researchers have now successfully designed
superconductors one atom at a time, creating new states of matter.

It the new superconductors can only be built one at time by scanning tunnelling microscopes, they won\'t be being produced in the kind of volume that would let them be of much use.

A nice complicated metal-organic complex that put the metal atoms in the right place to offer super-conductivity might permit production in useful volumes.

It won\'t be a new state of matter - just the same old solid state - but with the atoms better arranged.

Whilst you could do it that way it would be glacially^d^d^d^d^d^d
geologically^D^D^D^D^D^D^D^D^D cosmologically slow to obtain useful
amounts of the stuff. Any realistic bulk semiconductor material has to
be approximately self assembling even if it takes many cycles to do it.

It is interesting to create a small patch of designer material in 2D
with \"bulk\" properties that you can discover using the same technique.

But even making something 1000x1000 atoms across requires a lot of work.

Putting down a layer at a time is just about doable, putting down an
atom at a time is like pissing into the wind!

I never expected the solutions for wave-functions in 2D constrained
conductors to be anything other than an easily solved theory problem for
undergraduates but now with graphene and bucky balls the quantum
particle in a constrained box problem has become much less theoretical!

It\'s funny that posters here don\'t understand that if you make devices small enough, they can be built one atom at a time with useful results. The article is actually about a novel way to make superconductors.

Whatever. Forget it Jake, it\'s s.e.d.

Yes I though the same, but then compared the situation to modern pick an place machines.
On top of that we are moving toward ever smaller transistors etc, Moore\'s Law,
approaching a few atom size transistors?
So why not, should be cool, high speed too

For manufacturing, absolutely. A 15-mm square chip has around 10**15 atoms
per atomic layer, so even placing 1E6 per second, building 10-atom-tall
devices would take decades to make a single chip.

For development, there might be some very interesting physics to learn,
which might be buildable by other means.

I never expected the solutions for wave-functions in 2D constrained
conductors to be anything other than an easily solved theory problem for
undergraduates but now with graphene and bucky balls the quantum
particle in a constrained box problem has become much less theoretical!

And pHEMTs, both InGaAs and GaN, which have been in wide use for years.
