So if I'm understandin this right - they've figured out a way to produce a better-than-mosfet that is more efficient therby reduing power consumption as waste heat?
yes something like that...Quote:

Interesting, but as with all tech advances it could be years before it hits market, or never.
The EE Times article has a very 2D looking FET block model, so perhaps not something that can easily be integrated into modern FinFETs. Also, it's not clear what the switching speed of these TFETs are, or how easily they can be built with existing lithography. A quick search suggests people have been working on this material for at least 5 years :-

Might have to wait 5 more years for that phone/watch that lasts a week on one charge.

Getting a Pebble Time for Christmas and it might make a working week on a charge...
Funny, years ago I did an undergraduate dissertation on power mosfets. At the time the search was to increase the current and reverse voltage characteristics for applications such as motor control and so on. There were various technologies, one was the Vfet, which referred to in treading the junction area to support higher currents.
Now we are at the other end of the scale! :)
