81 Gigahertz Diamond Processor

TOKYO — Nippon Telegraph and Telephone Corp. (NTT) has developed a diamond semiconductor device that operates at 81 GHz frequency, more than twice the speed of earlier devices. The advance promises to make amplification in the millimeter-wave band from 30 to 300 GHz possible for the first time, NTT claimed.
Diamond is expected to be the next generation semiconductor material because of its high thermal conductivity, high breakdown voltage and high carrier mobility. Together, these characteristics makes diamond semiconductors most suitable for high frequency, high power devices.
But diamond semiconductors are prone to defects and impurities that have hindered development of prototype devices with performance close to the expected, theoretical performance of diamond semiconductor devices.
NTT is now working to further decrease impurities to improve the quality of diamond crystal. It is targeting devices with an operating frequency of 200 GHz and an output power of 30 W/mm.
I've always expected that there would be some new technology discovery that would break the normal timetable for processor speed increases that prevail in the industry. Although it seems the device they built isn't actually a processor, it should strike a note in any techie's head that big times are coming.

simply amazing.

Considering perfect diamonds can be made in a lab now, this kind of tech should take off pretty fast.

Like computer parts don't already costs enough without being made of diamonds...

At 5$ a carat, lab made diamonds aren't particularly expensive.

Dang. $5 per synthetic carat. Why dont they sell those in jewelry stores...

They will soon enough. And it's not synthetic, it's real diamond. Just not naturally occuring.

it is synthetic, which is a man made stone bearing the same physical optical and chemical properties as the natural stone. it is not a simulant, which just has the appearance of the stone.

dictionary.com definition of synthetic:

Produced by synthesis, especially not of natural origin

does the synthetic in "synthetic diamond" mean something else other than being produced by synthesis?
personally, i just thought that there are now two types of synthetic diamonds available, those that look natural and those that dont.
