Researchers Create Single-Atom Transistor
HardOCP ^ | Monday February 20, 2012 | Steve

Posted on 02/20/2012 11:43:03 AM PST by Ernest_at_the_Beach

For those of you that haven't seen this yet, Researchers from Purdue, the University of Melbourne and the University of New South Wales have created a working transistor from a single atom. Thanks to Robert for the link.

We have fabricated a single-atom transistor in which a single phosphorus atom is positioned between highly doped source and drain leads with a lateral spatial accuracy of ±1 atomic lattice spacing. We demonstrate that we are able to register source, drain and gate contacts to the individual donor atom and observe well-controlled transitions for 0, 1 and 2 electron states, in agreement with atomistic modeling of the device.

It has to have a teenie tiny point.

Sandia might have some.

Actually, I’ve been in the Micro-electronics lab there, some pretty small stuff.

LESS THAN $4.5k TO GO!


The funds raised in these FReepathons go to pay our current quarter expenses. But we're also going to try to replace some of our older servers and failing equipment this year so we're going to add a little extra to our FReepathon goals. John is estimating ten to fifteen thousand to do this and I'd like to get it all in place and working before the election cycle is fully heated up, so we'll try to bring in a little extra now, if we can, and the rest next quarter.

Nice, but can it make julienne fries?

Likely but they would be too small to see.

And it would take all day to make one mouthful.

What could possible go wrong, when the battery catches fire ...

Plus going to take a really small diameter solder :^)

LOL, some of the stuff I worked on required a wide field of view X20 binocular microscope and a $3000 Pace solder/desolder station with a vacuum pick up tool to handle the components............Glad I'm retired :^)

It's not just a transistor, it is a FET since it has a source, gate and drain connections. I wonder what it sounds like since FETs tend to sound like tubes although the obvious use is to line up a few billion to make a tiny but powerful microprocessor.

I don't understand this stuff at all....but I did work with the 360 assembler.

It has gonnta have some impact on puters.

Perhaps. Perhaps not. Time will tell.

In the book of Genesis it says:"And the Lord said, Behold, the people is one, and they have all one language; and this they begin to do; and now nothing will be restrained from them, which they have imagined to do." (referring to the tower of babel)

Makes one wonder how many angles can dance on the head of a pin!!! (grin)

The stuff we manufactured in the late 80s had diodes six mils across manually thermo-compression wedge-bonded with half-mil wire. The bonding pad on the diode was .0007 across. IIRC, we ran 60GHz through it as a switch.

Great, now all we need is single atom leads and we’re in business.

I hope the tax payers didn’t have to pay for this laboratory recreation expedition...

Ouch!
Seven layer boards with smc's that had to take 350 deg F and vibration was bad enough.

Just so long as they are all right angles!!!

If you use angles and they are infinitely acute, that could be a lot of them. If you use angels, I just don't know.
