AU creates worlds smallest + precise transistor

SYDNEY scientists have built the world's tiniest transistor by precisely positioning a single phosphorus atom in a silicon crystal.
The nano device is an important step in the development of quantum computers – super-powerful devices that will use the weird quantum properties of atoms to perform calculations billions of times faster than today's computers.
Michelle Simmons, of the University of NSW, said single atom devices had only been made before by chance and their margin of error for placement of the atom was about 10 nanometres, which affected performance.


Creating a single atom transistor isn't the breakthrough here. The real breakthrough is that they can position a single atom with a 1 atom accuracy. Usually the error rate for positioning these atoms was 10atoms^3 which meant in the past that reliable circuits etc couldn't be made.

pretty damn cool. it will be interesting to see what component manufacturers pickup the tech.

That's because 'cancer' isn't one disease. An increasing number of cancers are highly treatable.

Pfft who cares. We don't need no super computers. We already have unlimited graphics thanks to whats his face

So basically we'll have either extremely small CPU dies or extremely complex, incredibly cached up, many core CPUs at the same size. If this is able to be implemented into CPU construction eventually, it'll mean really powerful mobile CPUs, or thinner mobiles.

Welldone Australia that s*** is awesome.
Can't wait to install my first computer implant. Should I put it in my wrist for the mic or just have it straight in my cheek?

You aren't going to see this tech in computers any time soon. They made this transistor using an STM - that's going to be an extremely slow process. Now times that by the number of transistors in a modern CPU. A whole CPU made out of these would also be extremely unreliable. All it would take is one dopant atom diffusing and you're done (unless you operate near 0K).

Very cool proof of concept though.

What's his face was actually meant to give a presentation to some Surveyors / Spatial Scientists. Apparently they can adapt his game software to show our many, many, many million point ALS (3D Land / Ground / Building) data without falter or stutter. Not sure what ever happened to it, told the boss I was interested in seeing it, live... with our data. Don't think we heard back yet.
