Chipmakers Test Ferroelectrics as a Route to Ultralow-Power Chips

Supriyo Datta is a pretty top level semiconductor theory guy, so its a good chance theoretically this could work, but the place where tons of issues have come up over the years in using new materials is that they often lead to quality or defect issues in the manufacturing process that takes years to figure out.

Fwiw, Chenming Hu is a proponent of NC-FETs as well.

Also, GloFo has already fabricated FinFET NC-FETs.

oh interesting, was not aware of the term NC-FET -- so basically the ferroelectric material gives it the negative capacitance behavior... interesting.

Yup, the NC-FET essentially has the NC and positive capacitor in series to get a voltage amplifier, a clever way of subverting the Boltzmann limit :)

Also funny, I spent months trying to buy his book for one of my semiconductor device physics courses that was out of print, and finally bought it for like $180 on ebay.. it actually was worth it.. really well written book..

Could you please name the book for those of us that may be interested?

I'm not xt00, but based on age/out-of-printness I'm guessing it may be Datta's 1989 book "Quantum Phenomena (Modular Series on Solid State Devices, Vol 8)". His 1986 book "Surface Acoustic Wave Devices" is a distant second-best possibility, depending on what was in that one semiconductor device physics course.

Everything else seems to be in print still, though some are expensive (as typical of specialized books).

Was definitely part of the modular series, a small dark blue book.

It’s this one as the previous poster said. "Quantum Phenomena (Modular Series on Solid State Devices, Vol 8)".

It’s referenced to by many other books from what I recall. So I decided to go hunting for it — and found that the explanations in Datta’s book were better than many of the books that came after it. I’ll see if I still have the book someplace.

There's also a decent scan of the book available via b-ok.org.
