Didn't read the whole article, but haven't diamonds been manufactured for a while now? They sell manufactured diamonds called Diamonique on QVC all the time. Or is it that these diamonds are higher quality maybe?
I think the difference is that these are actually, really, genuinely diamonds. It was a great read.
I think the news is that these are gem quality (vs. made for tool use).
How very interesting. I work with CVD mahcines in the semiconductor business, and once mentioned the use of Methane in place of Silane (SiH4- we use to lay down layers of Polysilicon). I was met with silence, and at the time, I didn't even take it any further. Who knew? I don't know enough about carbon-based semiconductors as compared to silicon-based, other than it ought to work- they both fall into the right place on the chart. Todd
Very interesting read, especially regarding diamond semiconductors.
Thanks for the link, Scott, that was a great read. My favorite part:
Good to see. I learned about the DeBeers stranglehold and virtual monopoly while hunting for an engagement ring back in Febuary. Good luck to them. I'm sure DeBeers and co. will start calling them "fake diamonds" and continue to delude the public into thinking that diamonds are rare.
Diamonds have been manufactured for some time. Debeers gave up the industrial diamond market, but rumors aboud that they have some agreements with certain patent holders that keep sytnthetic diamonds out of general cosmetic circulation. Diamonds are the biggest scam in the world. When a man proposes he has to offer up "A girls best friend" engagement diamond. However, does the groom get 'Man's best friend"? An engagement dog?? No. Life just isn't fair.
Todd, are you still working for that company that starts with an "A"? (I was laid off by them last Sept. if you don't remember). Diamond semiconductors would be very cool. I wonder if doping the material would be more difficult than it is with silicon, though. I'm not a process/device guy, so I have no idea.
To quibble just a bit Chung, Debeers is technically the major player in a ‘cartel’, not a monopoly. This is because diamonds are available in places other than those controlled by DeBeers (Russia being a notable example). However they manage to continue to set the world price by both having a very large share of the gem market and getting other gem-quality diamond producers to go along with them.
Lew, Thanks for the correction, I did mean a cartel. It's just that whenever I think of cartel, I think of a bunch of sweaty guys dealing drugs, while when I think of monopoly I think of a short white guy with a tophat, an image which I think more applies to diamonds. Oh well.
For people who want to avoid the moral quandry associated with buying DeBeers diamonds, there are always Canadian diamonds: http://www.canadadiamonds.com
