First Principles Study

Nanodiamonds of different sizes doped with B and N impurities are studied by density functional theory. We find that the most stable sites for the B and N dopants are different. The substitutional B tends to stay in the middle region of a nanodiamond, while the energetically preferable site for N is on the surface of the nanodiamond. The chemical bonding and electronic properties of the B- and N-doped nanodiamonds are also discussed.
