Department/Abbreviation: KEF/FPOV

Year: 2020

Guarantee: 'doc. RNDr. Libor Machala, Ph.D.'

Annotation: The main aim is to learn students basic methods of study of physical properties of materials. Students are familiarized wit experimental techniques for characterization of surfaces as well.

Course review:
1. Ideal and real surface of solid matter. Crystal structure, purity, achievement of atomically pure surfaces, adsorption, desorption, electron structure of surfaces, types of bonding, electronegativity. 2. Work of exit. Theory, dependence on kind of matter and surrounding interactions, measuring and practical reason to measure work of exit. 3. Effect of heat thermoelectron and thermoion emission, surface ionization. 4. Incidence of electromagnetic irradiation. Photoelectron emission, fundamentals of photoemission spectroscopy. 5. Incidence of electrons. Secondary electron-electron emission, electron induced desorption, elastic reflection and diffraction of electrons, inelastic interaction of electrons with a surface, fundamentals of electron spectroscopy. 6. Vibration excitation on the surface of solid matter 7. Methods of study of surfaces of solid matter Microscopy (AFM, STM, UHV STM), X-ray photoelectron spectroscopy (XPS), Conversion electron Mössbauer Spectroscopy (CEMS), BET physisorption, chemisorption, low energy electron diffraction (LEED), surface X-ray diffraction (SXRD), Secondary Ions Mass Spectroscopy (SIMS). 8. Physics of surfaces of nanoobjects, selected application of surface nanostructures (e.g. photocatalysis of water splitting).
