Opis

Understanding the structural organization of materials at the atomic scale is a lo- standing challenge of condensed matter physics and chemistry. By reducing the size of synthesized systems down to the nanometer, or by constructing them as collection of nanoscale size constitutive units, researchers are faced with the task of going beyond models and interpretations based on bulk behavior. Among the wealth of new materials having in common a "nanoscale" ngerprint, one can encounter systems intrinsically extending to a few nanometers (clusters of various compo- tions), systems featuring at least one spatial dimension not repeated periodically in space and assemblies of nanoscale grains forming extended compounds. For all these cases, there is a compelling need of an atomic-scale information combining knowledge of the topology of the system and of its bonding behavior, based on the electronic structure and its interplay with the atomic con gurations. Recent dev- opments in computer architectures and progresses in available computational power have made possible the practical realization of a paradygma that appeared totally unrealistic at the outset of computer simulations in materials science. This consists inbeing able to parallel (at least inprinciple) any experimental effort by asimulation counterpart, this occurring at the scale most appropriate to complement and enrich the experiment.

Blurb

The book covers a variety of applications of modern atomic-scale modeling of materials in the area of nanoscience and nanostructured systems. By highlighting the most recent achievements obtained within a single institute, at the forefront of material science studies, the authors are able to provide a thorough description of properties at the nanoscale. The areas covered are structural determination, electronic excitation behaviors, clusters on surface morphology, spintronics and disordered materials. For each application, the basics of methodology are provided, allowing for a sound presentation of approaches such as density functional theory (of ground and excited states), electronic transport and molecular dynamics in its classical and first-principles forms. The book is a timely collection of theoretical nanoscience contributions fully in line with current experimental advances.
