First principles calculations of Structure and electrostatic properties of non ligated CdSe nanoclusters
Anteneh G Tefera, Mogus D Mochena, Elijah Johnson +1
Structural and charge relaxation of nanoclusters of CdSe of diameter 1-2 nm are studied with first principle calculations. The relaxations cause significant distortions of smaller…
Doping icosahedral Fe with 3d transition elements
Anteneh G. Tefera, Mogus D. Mochena
Our density functional theory calculations for Fe_{13-n}M_{n} for M = Sc, Ti, V, Cr, Mn, Co, Ni, and Cu up to n = 4 show that the icosahedral symmetry of Fe13, albeit minor changes…
Nucleation and cap formation on symmetric metal nanocatalysts: A first step towards chirality-controlled single-walled carbon nanotube growth
Anteneh G Tefera, Mogus D Mochena
Symmetric minima of surface potential energy of a nanocatalyst act as nucleation sites for chirally selective initial growth of single walled carbon tubes at low temperatures. The…
Ground-state properties and molecular theory of Curie temperature in the coherent potential approximation of diluted magnetic semiconductors
Sze-Shiang Feng, Mogus Mochena
Using spin-1/2 description of valence holes and Kondo coupling between local spins and carriers, GaAs-based III-V diluted magnetic semiconductors (DMS)are studied in the coherent p…
Manganese nanoclusters and nanowires on GaAs surfaces
Mogus Mochena, P. J. Lin-Chung
We have computed the local magnetic moments of manganese and neighboring arsenic for various cluster configurations on the (001) surface of GaAs bulk crystal using a cluster of 512…
