The aim of the course is to introduce modern techniques for materials characterisation, particularly surface characterisation, that are used for both academic and industrial research and development.
After a successfully completed course the student should be able to:
motivate and discuss choice of methods for imaging and analysis by comparing performance and judging usefulness of different methods for a given problem,
critically judge the choice of method and conclusions in scientific papers where methods for imaging and analysis have been used to solve specific problems,
describe the principles, including the interaction between probe and sample surface, for surface imaging and measurement using electron, light, interference and scanning probe microscopy, and describe the design of some instruments, and use a simple scanning electron microscope (SEM),
describe and evaluate the quality of the results from surface imaging and measurement, and describe the effect of instrument settings and performance,
describe the principles of surface analysis of selected methods, including X-ray, electron, ion, vibration and optical spectroscopy, and describe the design of some instruments,
explain and compare possible information and performance of some methods for surface analysis based on interaction between activating surface irradiation (e.g. electrons, ions, or X-rays) and sample surface and on instrument settings and performance,
describe the principles of depth profile analysis using ion etching/sputtering and of imaging, analysis and sample preparation using a focused ion beam (FIB),
describe the principle of transmission electron microscopy (TEM) and what kind of information and analysis results this method yields.
Imaging, description and measurement of surfaces: methods included are e.g. light optical microscopy (LOM), SEM, scanning probe microscopy (SPM, STM and AFM), optical method for surface profiling (interference microscopy) and mechanical scanning probes. Chemical analysis of surfaces and depth profiles: methods included are e.g. X-ray spectroscopy (EDS, XRF), electron spectroscopy and diffraction (ESCA/XPS, Auger, EBSD), ion mass spectroscopy (SIMS), ion beam spectroscopy (RBS and ERDA), optical spectroscopy (GD-OES) and vibration spectroscopy (Raman and IR). Introduction to TEM for analysis of a materials internal structure, including description of sample preparation and analysis using EDS. FIB for imaging, analysis and sample preparation.
Lectures, seminars, assignments, laboratory work.
Written exam at the end of the course (8 hp). Approved laboratory work and assignments (2 hp).
