    I read this story earlier today, and i can already tell that 90% of the above posters havent read it.

    If they did they would know that these are manufactured diamonds using relativly new processes that allow for some large diamonds.

    Being manufactured they are rather cheap. The jewel grade stones will be sold at about half fo what debeers is selling thier diamonds for.

    The big falacy about diamonds is that they are scare. They are, in fact, in great abundance but most of the world's supply is controlled by Debeers. They trickle diamonds onto the market keeping the price artificially high.

    To summarize.

    1. We can now make great looking diamonds for cheap. (2 different methods of doing so)
    2. They can be formed into anything from gemstones to about 4 inch wide(so far) diamond wafers.
    3. There are 2 forms of doping in the process of creating the diamonds that allows for + and - parts (couldnt think of the word) that means we now have the building blocks of logic for diamond based chips.

    The big point behind putting chips on diamonds is that diamonds are the best known conductors of heat. That means that the chip can be severely cranked up without melting.

    The idea is to sell gemstones until they can start making semiconductor blanks. The diamonds will be comparatively cheap, since the vast majority of the cost to produce the diamonds is fixed.

    As to DeBeers, I'm sure they'll come up with some marketing angle. Personally, after taking a university honors course in gemology, I learned that the way to tell the difference twixt 'real' and 'fake' gemstones was the 'real' ones were full of crap.

    It is unclear, at best, whether or not diamond has any advantages for mainstream processing. Just because diamond has higher thermal conductivity doesn't mean that it can magically solve all of our problems...without knowing what kind of carrier mobilities can be acheived you can't conclude anything. It might turn out that diamonds are actually far worse than silicon for processing applications. And then there are all of the potential fabrication problems. The lack of good dopants. The lack of a stable native oxide (instead of silicon dioxide, you have carbon dioxide...). How are you going to etch 10nm features into diamond? The article talks of a lack of interest from mainstream companies like Intel. I would take this as a very bad sign for diamond processors...with the scope of Intel/IBM/AMDs research efforts, if they're not looking into something, then its probably not worth researching. Diamonds might have some very useful applications in optical devices...but don't expect to see them inside your desktop computer.
    • Well, if you read the article you would know that
      the doping issues seem resolved, and that diamond
      without doping is an insulator. So that takes care
      of most concerns. On the other hand, the article

      It might not be very good. And mobility issues

    Look at the periodic table.

    Silicon is in the same family as Carbon (same column)

    As indicated by Mendeleev, the creator of the periodic table, elements in the same family share the same properties.

    Carbon and Silicon share the ability to form chains of arbitrary length...this property gets weaker as you travel down the family, from infinite chains (Carbon) to max of 10 (silicon)

    It only follows, naturally, that if silicon is an "okay" semiconductor, just as it is at forming repeating chains, that carbon, which forms better chains, would also be a better semiconductor.

    Diamonds are just a pure carbon with a special crystal structure...so, of course, they should be semiconducting. Graphite may be also, following the same logic.

    It looks like the big breakthrough is the CVD technique. The old Russian design had the problem of letting in too much nitrogen and creating only yellow diamonds. They have improved the technique but it is still harder to make clear diamonds. I read that they were going after the colored market since colored natural diamonds are more expensive. Plus it must be easier to add color with new elements than remove all the yellow. (They can add different elements to get different colors.) Expect the market in colored diamonds (especially yellow) to get cheap. (Kobe should have waited...) Of course the real volume is in clear diamonds. Hopefully the CVD technique can make cheap clear diamonds. I know they said $5 a carat, but I wouldn't trust Wired.

    Interesting article, but it's missing some of the point. There are two issues here: fabricating substitute "gem" diamonds for jewelry, or fabricating diamond for the semiconductor industry..., or diamond coatings for wear resistance, biocompatible implants, etc. These are an entirely different beast.

    CVD diamond, even in with the best of reactors, is limited by growth rates. Working with thin films is, at the moment, the only way to go. You can also only get single crystal diamond by growing on a previously obtained single crystal diamond- as they mention in the article. This is seriously limiting, and they don't mention the growth rates in the article. 5$ a carat is such a BS guess it's not even funny.

    CVD diamond grown primarly on Si wafers, and on some specially coated Si wafers, is the way diamond (which is polycrystalline, with different grain sizes giving very different diamond properties) is going to be used in the near to far future. Our group just got a RD 100 award (not that I give that much creedence to those, but it's recognition) for coating 4" wafers with diamond, and we're going up to 8" next year.

    The biggest problem is with the electronic properties of the diamond. Sure, it's a great thermal conductor. But... ahem.. it also needs to be a great electical conductor- and have decent mobilities- to be used in actual electronic devices. You can dope diamond with boron to make it p-type, but the conductivity isn't all that high, and the mobility even less, in polycrystalline diamond due to defects and grain boundaries, etc. We've made n-type nanocrystalline diamond with nitrogen, which shouldn't work, but does, and we're still trying to figure out the conduction mechanism.

    Thin film diamond is really going to shine for a few particular uses- MEMS (it has extremely low friction/stiction/wear), bio-devices, chemically resistant devices, etc. In all of these cases, even conductive MEMS driven by diamond electronics, borderline and not great electronic properties are fine. (Think Si TFT's for your comptuer display- it's not single crystal Si, obviously, but still has a great potental for other uses.)

    There is no way to dope single crystal n-type. People are trying very hard to do this. Some people think they have gotten phosphorous to work slightly, but the growth is very difficult, and the work hard to reproduce. (our doping probably occurs in the grain boundaries, and we think we have actual grain boundary conduction vs. traditional doping processes.) That is a far bigger barrier than just growing BIG DIAMONDS. This article is just some PR spin press release that doesn't really say anything. (As I get more jaded, I see that that is all they really ever are). Just because you can't make Intel processors out of diamond doesn't mean you can't utilize diamond for a large number of exciting applications.

    Remember: bigger is not better. Although I personally do like the idea of freaking out DeBeers.

    Pull me a diamond boule, and I"ll be impressed.

      RTFA...or, to save you the trouble, from the fifth page of the article:

      The third big challenge has been the most daunting for materials scientists: To form microchip circuits, positive and negative conductors are needed. Diamond is an inherent insulator - it doesn't conduct electricity. But both Gemesis and Apollo have been able to inject boron into the lattice, which creates a positive charge. Until now, though, no one had been able to manufacture a negatively charged, or n-type, diamond with sufficient conductivity. When I visit Butler in Washington, he can barely contain his glee. "There's been a major breakthrough," he tells me. In June, together with scientists from Israel and France, he announced a novel way of inverting boron's natural conductivity to form a boron-doped n-type diamond. "We now have a p-n junction," Butler says. "Which means that we have a diamond semiconductor that really works. I can now see an Intel diamond Pentium chip on the horizon."

I have planned on venting them out the Window but I have to handle the bug and security problem there at the same time.

    A bit of googling turned out this page [sei.co.jp] with pictures of artificial diamond gems, and wafers. Seems like Sumitomo Electric has some wafers larger than the few milimiters mentioned in the article.

    I wonder how far along the Japanese are in this research...

    Oddly absent -- though perhaps not so considering the source is Wired -- is any consideration of the significance of cheap diamond for optics. Diamond has a substantially higher refractive index than glass and is less subject to thermal and mechanical deformation than glass. What that would mean in practice would require a deeper knowledge of optics than I have, but it sure would be interesting to see what kind of lenses and prisms could be made out of it for cameras, telescopes, and microscopes.

    I love diamonds. I really do. Staring into a diamond is like standing in a room full of mirrors. Even uncut diamonds are beautiful - I've got a nice uncut diamond brought back from Africa by a relative generations ago.

    But it's always irritated me that the price of diamond has been kept artificially high by DeBeers. Given a choice between an artificial diamonds and an artificial price.... I'll take the artificial diamond.

    Besides, it's not as if I'd ever be able tell the differance. Unless of course DeBeers starts supplying a fourier transform infrared spectrometer free with every diamond. Which, as I'm a techie who likes technical toys, is the only thing that would make me cough up the DeBeers premium.
