Studies on electric polarization open potential for tinier devices |
A very interesting one. It might be a breakthrough in nanoscale ferroelectricity:
ARGONNE, Ill. (June 11, 2004) — Researchers from the U.S. Department
of Energy's Argonne National Laboratory and Northern Illinois
University have shown that very thin materials can still retain an
electric polarization, opening the potential for a wide range of tiny
devices.
The researchers found that the ferroelectric phase – the ability to
hold a switchable electric polarization – is stable for thicknesses as
small as 1.2 nanometers, one-billionth of a meter, or a size several
hundred thousand times smaller than the period at the end of this
sentence.
Previous studies had found that, as the material became too thin, it
quit being a ferroelectric. These new results, however, suggest that
small thicknesses do not pose a fundamental problem to building very
small devices based on these materials. The research is published in
the June 11 issue of Science magazine.

Building one latching RAM cell is research. Building a 125 megabit
latching RAM chip and ganging nine of them together into a 125
megabyte RAM with parity check is technology. Successfully doing that
a few million times is engineering. You can sell engineering.
How many times has cancer been cured in the lab? The number of "new
hopes for cancer cure" would choke an elephant. Get real. They are
lying to you.

Well, I agree that far not everything what is done in the lab finds
(or works) finally when implemented to the customer product. But
that's exactly why we need fundamental research at universities,
because 1% of developments still work.
