Not seen mention of this here yet but the first electronic switch
transistor built by moving atoms around is now just 7 atoms across.
Makes you wonder how they do the phosphorus doping!

You have to love the journalists mention of the single silicone (sic)
crystal used as the foundation.

A slightly less garbled version is online at UNSW website.

That's probably super radiation sensitive. One wee cosmic ray ... PHUT
.... "Please contact your IT department" ... then the IT guy comes with a
bucket of atoms and molecules, all nicely sorted into little plastic
bins, and inserts the one that had vaporized :)

A boob job on a transistor? This I've got to see :)


Got a security warning and shutdown on that one for some reason.

Quantum computing will be hairy for the foreseeable future, but this is
really a big step forward in miniaturisation even if there is no
realistic prospect of it ever being production line stuff.

I blame the spell checkers. The words are more or less identical to the
university press release apart from "silicone".

Weird. It is a genuine site and there is a nice STEM micrograph of the
thing with the atoms all visible including on the bondout wires.
Looks a bit like a space invader ;-)

A bit of a pain soldering it to a PCB...
