Abstract

Metallic nanoparticles are an important class of materials which exhibit properties different from bulk materials. At small sizes nanoparticles form in non-crystalline structures such as icosahedron and decahedron along with crystalline fcc structures. In this presentation, we will describe the geometry of the various structures and discuss the energetic stability of those structures. Theoretical studies are necessary to understand these systems and gain insight into physical process. Finally freezing and growth simulations of silver nanoparticles will be discussed.
