The designer optical resonances of metal nanoshells
Metal nanoshells consist of a dielectric or semiconducting core coated with a metallic layer of nanometer scale dimensions. Gold nanoshells with silica cores were fabricated by first attaching gold colloid to the surface ...
Nanoparticle assemblies and interactions
Silica nanoparticles coated with functionalized organosilane molecules are used as substrates for the formation of assemblies of gold nanoparticles. In an assembly of nanoparticles, the optical response of each nanoparticle ...
Triplet exciton dynamics in conjugated polymer films
A thorough knowledge of the excited state dynamics in conjugated polymers is necessary for efficient use of these novel materials. Triplet excitons are believed to play an important role in conjugated polymer-based device ...
A density-functional study of ammonia chemisorption on the gallium(5) arsenic(5) cluster: Single and double adsorptions
I present a computational study of the reactivity between NH$\sb3$ and the $\rm Ga\sb5As\sb5$ cluster. A single NH$\sb3$ molecule approaches several sites on the cluster and the system is relaxed to its local lowest energy ...
