Chemical vapor deposition carbon doping

To solve the problem, we considered that a boron-doped diamond, BDD, is the most ideal anode for electrochemical fluorination and so we focused on a BDD electrode. The BDD film is prepared on a carbon substrate by hot-filament chemical vapor deposition with doping boron into the diamond lattice, adding trimethylboran gas to a mixed gas of methane and hydrogen. Since a BDD film has a high electric conductivity and stability of structure such as diamond, it is expected that a BDD electrode can be used as a new anode material in this...

Boron-doped chemical-vapor-deposited diamond is an exceptionally inert carbon electrode with a very wide potential window and very low voltammetric background current. [A. E. Fischer, Y. Show, and G.

Cyclopentadienyl compounds have been thoroughly investigated as suitable precursors to rare earth doped semiconductors in MOCVD (metal-organic chemical vapor deposition) or MOVPE (metal-organic vapor phase epitaxy) processes [283]. The use of btsa complexes for the same purpose has appeared in the literature very recently [285]. Typical process conditions are shown in Scheme 14. It was found that the carbon contamination of the deposited metal is less in the btsa case.

For some time, mixtures of H2 and natural gas have been used for chemical vapor deposition (CVD) growth of diamond-like carbon (DEC) films. It is now possible to use this technique to grow diamond seed crystals to produce clear, perfect colorless diamonds. Diamonds grown by the high-pressure methods are invariably doped and thus colored. One company, Apollo, has used the CVD technique to grow 1-ct diamonds. 

Doped diamond is the alternative carbon material to glassy carbon for ozone generation [20,21], but the technology is much less developed. Boron-doped diamond is prepared by chemical vapor deposition and has been used as an anode when (i) deposited as a thin film on substrates such as silicon, titanium, or niobium or (ii) fabricated as a bulk plate - for example. Element Six supplies Diafilm EP as a free-standing polycrystalline plate capable of supporting current densities of >1 Acm [25]. Typically, the boron-doping concentration is 10 °-10 atoms cm when its resistivity is of the order of 0.05 cm. These boron-doped...
