2. Chemical vapor deposition - Wikipedia

   en.wikipedia.org/wiki/Chemical_vapor_deposition

   CVD diamond growth typically occurs under low pressure (1–27 kPa; 0.145–3.926 psi; 7.5–203 Torr) and involves feeding varying amounts of gases into a chamber, energizing them and providing conditions for diamond growth on the substrate. The gases always include a carbon source, and typically include hydrogen as well, though the amounts ...

3. Crystallographic defects in diamond - Wikipedia

   Around the year 2000, there was a wave of attempts to dope synthetic CVD diamond films by sulfur aiming at n-type conductivity with low activation energy. Successful reports have been published, [ 64 ] but then dismissed [ 65 ] as the conductivity was rendered p-type instead of n-type and associated not with sulfur, but with residual boron ...

4. Synthetic diamond - Wikipedia

   en.wikipedia.org/wiki/Synthetic_diamond

   Lab-grown diamonds of various colors grown by the high-pressure-and-temperature technique. A synthetic diamond or laboratory-grown diamond (LGD), also called a lab-grown diamond, [1] laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond, is a diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is ...

5. Material properties of diamond - Wikipedia

   en.wikipedia.org/wiki/Material_properties_of_diamond

   Additionally, diamond is unusually lipophilic, meaning grease and oil readily collect and spread on a diamond's surface, whereas in other minerals oil would form coherent drops. This property is exploited in the use of grease pencils , which apply a line of grease to the surface of a suspect diamond simulant .

6. Nanodiamond - Wikipedia

   en.wikipedia.org/wiki/Nanodiamond

   Boron-doped diamond (BDD) produced by energy-assisted (plasma or hot filament, HF) Chemical Vapor Deposition (CVD) processes is a good candidatein Dopamine detection, however it is not selective towards some interferents.

   Here is what the most popular diamond shapes for engagement rings mean. While reading, think about which shape reflects you and your partner. Round Brilliant Cut: Traditional and Elegant

9. Carbon film (technology) - Wikipedia

   en.wikipedia.org/wiki/Carbon_film_(technology)

   They include plasma polymer films, amorphous carbon films (diamond-like carbon, DLC), CVD diamond films as well as graphite films. Carbon films are produced by deposition using gas-phase deposition processes, in most cases taking place in a vacuum: chemical vapor deposition, CVD or physical vapor deposition, PVD.
