A basic understanding of (1) structural properties of crystalline materials, (2) electrical properties of metals, (3) the electronic properties of undoped and doped semiconductors and (4) atomistic mechanisms of dielectric and magnetic materials was gained.
The operation of electronic devices is based on the properties of the materials from which they are produced. What reason specifies a material to be a conductor or insulator and why does a semiconductor serves as basic material for microelectronic devices? The course “electronic materials” shall generate a fundamental understanding of the electronic properties of metals and semiconductors. For this we rely on the cohesion of solid materials (chemical bond) and the crystalline order which is present in many cases. Exemplified by metals a model for the origin of the electrical resistance is developed for DC and AC currents. After discussing the miscibility of metals for implementation in alloys some significant applications are presented. Relating the semiconductors the band gap is introduced and an overview of the relevant materials is given. The central chapters concerning doped and undoped semiconductors deal with the electronic properties and the possibility for tuning them in a wide range according to the application. The section concerning the fundamental aspects ends with a detailed discussion of physical mechanisms of electric transport in semiconductors. Two further important electronic materials are dielectric and magnetic materials. For both types field and material equations are introduced, the polarization types are discussed and finally the important family of both ferroelectric and piezo-electric as well as diamagnetic, paramagnetic, and ferromagnetic materials are presented.
