Spectroscopic methods for non-destructive diagnostics
FEKT-DKC-FY2Acad. year: 2020/2021
The subject of the seminar are methods, dealing with the description, experimental investigation and localisation of defects. Main topics cover transport and stochastic processes, non-destructive diagnostics, noise diagnostics, partial discharges, acoustic emission, dielectric relaxation spectroscopy, microscopic techniques, spectroscopy, luminescence.
Learning outcomes of the course unit
After the course, students should be able to distiguish different types of transport processes, understand the physical mechanisms of fluctuation processes and the excess transport of carriers. They should also have an overview of basic diagnostic methods and should be able to choose and use appropriate diagnostic techniques to study a particular problem. Based on these tools, the students should be able to design and develop diagnostic methods for the individual particular applications.

The objective of the course is the description and analysis, of transport, relaxation and stochastic mechanisms in solids. Students will learn the basic methods for study of these processes and with the basic methods of their measurement. The key objective of the seminar is, however, not so much a mere acquisition of theoretical and experimental finding but rather a deeper understanding of the physical nature of all three spectroscopic methods and the ability to use and develop these methods for practical applications.
