Course detail

The subject is oriented on the description and determination of transport, relaxation and stochastic processes in solids. Students will learn the basic methods in reliability analysis, degradation and noise and dielectric spectroscopy.

After passing the course students should be able to distinguish between stationary and non-stationary processes, to understand physical mechanisms of noise and excess charge carrier transport and to design and determine reliability parameters of the device under test. Furthermore they should understand the nature of polarisation processes at the microscopic level including their mathematical description and staring from this background information they should be able to choose the most suitable dielectric ansd insulating material for the application concerned.

The subject knowledge on the Bachelor´s degree level is requested.

The objective of the course is to provide a survey of methods dealing on one side with the localisation and description of defects and their experimental investigation and on another side with the behaviour of dielectrics in electric fields and with their applications. Main topics cover transport and stochastic processes, noise non-destructive spectroscopy, non-destructive diagnostics, reliability tests, physical nature of polarisation in dielectrics, polarisation mechanisms at the microscopic level, mathematical and physical description of dielectric polarisation, overview of dielectric systems currnetly used in electrical engineering.
