Disordered Materials ― An Introduction

The teaching of solid state physics essentially concerns focusing on crystals and their properties. We study crystals and their properties because of the simple and elegant results obtained from the analysis of a spatially periodic system; this is why the analysis can be made considering a small set of atoms that represent the whole system of many particles. In contrast to the formal neat approach to crystals, the study of str- turally disordered condensed systems is somewhat complicated and often leads to relatively imprecise results, not to mention the experimental and computational e?ort involved. As such, almost all university textbooks, - cluding the advanced course books, only brie?y touch on the physics of am- phous systems. In any case, both the fundamental aspect and the ever wider industrial applications have given structurally disordered matter a role that should not be overlooked. The study of amorphous solids and their structure, stability and properties is a vibrant research branch; it is di?cult to imagine how any physicist, chemist or engineer who has to deal with materials could possibly ignore this class of systems.

Paolo M. OSSI (born in Milan, 1953) PhD in Solid State Physics, is Associate Professor of Physics of Matter at the Dipartimento di Ingegneria Nucleare, Politecnico di Milano. His current research interests include the structure of metastable condensed systems, the interaction between energetic photon and particle beams and solids, the properties (in particular structural and mechanical) of thin films, both metallic and ceramic, deposited in the presence of energetic beams. Paolo M. Ossi is author, or co-author of more than 100 scientific papers, besides many contributions to international Conferences, Workshops and Symposia.
