Main themes
The teaching will cover the following topics: - defects in inorganic solids and their formation mechanisms. - description of the chemical bond in inorganic solids (band theory) - description of electrical properties (conductors, semi-conductors, superconductors), magnetic, optical and photo-physical properties of principal inorganic solids, and the current applications in the growing domain of functional materials.
Aims

At the end of this learning unit, the student is able to :

1 This course is directed to students having a basic formation in inorganic chemistry and aiming to complete their formation by advanced notions in physical chemistry of functional inorganic materials. It aims at giving a fundamental understanding of chemical bonding in solids and at illustrating the various applications that result. The functionality associated to molecular electronics is also covered based on an orbital and structural approach.
