Atomistic Computer Simulations of Ceramics and Glass

Over the past few decades, computer simulation techniques have been developed as both a complement and a supplement to experimental probes of atomic scale behavior in solids.  In this seminar, we will describe the application of such techniques to a diverse range of phenomena in both oxide materials, both crystalline (ceramics) and non-crystalline (glasses).


After a brief introduction and overview, we will illustrate the wide range of problems which can be addressed through the following examples: (i) comparison and contrast of point defect interactions in Sr-doped zirconia and Gd-doped ceria; (ii) calculation of elastic moduli in silicate glasses and the straining to fracture in vitreous silica; and (iii) the adsorption of water on the surface of bioactive glasses.   Each example uses a different computer simulation technique, highlighting the point that the best technique to be employed depends on the nature of the problem to be tackled.
