21/09/2001· The electronic properties of the 7-1 structure of a gold nanowire, which is the simplest structure among possible helical multi-shell nanowires, are examined. Density of states (DOS) and crystal orbital overlap population (COOP) analyzes at the extended Hückel level of theory show that the contribution of the inner gold-atom row to the electric conduction and structural strength is small. The outer tube is responsible for both the structural stability and the electric

The Electronic Structure of Platinum-Gold Alloy Particles,

Although the platinum-gold (Pt-Au) phase diagram shows a wide miscibility gap due to limited mutual solubility of the components, small particles (< 3 nm) form homogeneous alloys because all atoms retain their atomic electronic structure, and rehybridisation due to band formation does not take place. Supported Pt-Au catalysts are often superior to those containing Pt alone for low-temperature,
