Syllabus of tutorials:

Excursion to the Institute of Physics of the Acad. Sci. of the Czech Republic (experimental determination of crystal structure, diffraction methods)

Excursion to the Institute of Hydrodynamics of the Acad. Sci. of the Czech Republic (electron microscopy, determination of the concentration of solids in aqueous media using gamma rays, measurement of polymer viscosity)

Laboratories of the Physics Department CTU: measurements of solar cells characteristics, laser microscope (surface roughness determination), study of moisture processes in capillary-porous materials

Measurements of thermic parameters and their changes with moisture content

Study Objective:

Basic information on the solid state physics, on the methods of structural investigations, and on some technically important processes in solids The aim of the course is to broaden the students' knowledge of the physical essence of the discussed processes, which is followed by practical procedures of design and dimensioning of structures in others specialized courses.
