Novel materials are a key to new technologies. Increasingly, technologies are becoming materials limited, so far new industries to develop, it is essential to discover materials with improved properties. Considering the advances in computational methods and computer hardware over the last few years, it is not surprising that modeling is playing an ever increasing role in the search for new materials. Material-specific theory, especially computational theory, is being used to understand the properties of novel materials in microscopic terms, and the understanding thus gained has often proved essential for the optimization of the known and the search for new materials.
The electrical, magnetic and optical properties of materials are controlled by their composition and structure; the structure and also strength of materials are determined by the chemical bonding between the atoms. Hence, “the chemistry controls the physical properties”.
At the root of all of these properties are the electrons: Valence electrons are responsible for the chemical bonding, conduction electrons for the electrical properties and both types of electrons are responsible for the magnetic and optical properties. The valence electrons can be described quite accurately without the use of adjustable parameters, that is ab initio, by an effective one-electron Schrodinger equation derived from a so-called local density approximation (LDA) to the density-functional formalism (Khon-Sham equation). Also the conduction electrons can be described by such a one-electron Schrodinger equation, although for nearly localized d or f-electrons the LDA is merely a first, rough approximation.
