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.

First Principles Study

We systematically investigated the structural stability and electronic properties of silicene-like nanotubes by potassium atoms encapsulated using density functional theory. The calculations show that all the structures of KnSi8(n+1) (n=2-12) nanowires are stable, the structural stable is proportional to the lengths of the nanowires. Electronic population analysis shows that K atoms gain electrons and Si atoms lose electrons as a whole, some electrons transferred from Si to K atoms. Because the peaks of d levels in DOS are contribution from the 3d hybridization levels of K and Si atoms, the magnetic moments derived from the orbitals hybridization. Maybe these kinds of nanowires will play an important role in spintronics and nanoelectronics.
