Learning outcomes
Problematics inherent to building an ordered tridimensional network of atoms, ions or molecules and limitations imposed by the stoichiometry of the material. Peculiar properties of hydrides (due the the size of hydrogen), carbides and nitrides (due to their high valence), borides (due to catenation tendency of boron) and oxides (due to the relatively low-valence of oxygen). General methods of synthesis for bulk materials, films and single crystals. Methods of characterization of materials. Structure-properties relatioships. The use (or potential applications) of some functional materials are critically analyzed with the help of a few most significant examples.
