Summary: Oren's Thesis Calculus Summary
Abstract
There are four principal categories of studies:
1. Hydrogen diffusion in Diamond crystals.
2. Hydrogen molecule diffusion in Diamond crystals.
3. Hydrogen diffusion in semi-frozen diamond.
4. Growth of Nano-Diamond in amorphous carbon.
1 Hydrogen diffusion in Diamond crystals.
Two samples of perfect Diamond crystals. One of them a 2 x 2 x 2 unit cells,
i.e. 64 carbon atoms. The second consists in a 3 x 3 x 3 unit cell crystal with
216 carton atoms. A different number of hydrogen atoms were introduced.
The original place of the hydrogen was the tetrahedral interstitial site (Td).
