Branislav Grančič, RNDr., PhD.

The student will first get acquainted with the technical possibilities of achieving vacuum, its measurement and control of working gases. He will gain a comprehensive knowledge of physical methods of preparation of thin films (evaporation, sputtering, arc evaporation, pulsed laser deposition), where he will be explained in detail the physical aspects of the processes. The student will gain information about the growth of thin films, the influence of deposition parameters on the structure and properties of films. In the last part he will be introduced to the possibilities of creating functional structures in films using ion treatment and lithographic methods.

vacuum pumps, scales and flow controllers, Langmuir probe, mass spectroscopy, evaporation, DC and RF sputtering, magnetron, glow discharge, plasma parameters, high energy pulses (HiPPMS), pulsed laser deposition, laser optics, ablation mechanism, arc evaporation, cathode macroparticle filtering, thin film growth, surface energy, thermodynamic nucleation model, zonal models, texture, epitaxy, focused ion beam, nanotubes, electron lithography, optical lithography

By completing the course, students will gain an overview of selected analytical, spectroscopic and microscopic methods used for studies of solids in terms their structure, composition, surface topography and other properties.

Acquisition of skills in registration and data processing by computer, measurement of electrical and magnetic quantities. Physical interpretation and written / graphic presentation of processed results.

In the initial two or three exercises, joint acquisition of skills and measurement with analog and digital devices (oscilloscope, digital multimeter, A / D converter), processing of measured data by computer. This is followed by five to six separate laboratory works on electricity and magnetism selected from the offer: electrical properties of substances – electric bridges, Hall effect; electric field mapping; magnetic field mapping – air coils; electromagnetic induction – transformer; electrical RLC oscillations – transient RLC phenomenon, serial and parallel RLC circuit; magnetic properties of substances – hysteresis loops, permeability of substances, separation of magnetic losses; fuel cell; determination of the specific charge of an electron (e / m0).

The student will understand principles of electric and magnetic phenomena and the laws describing them. He/she will be able to calculate topology of electric and magnetic fields in rather simple situations, calculate properties of components based on application of electric and magnetic fields, including electric circuits. He/she will understand relationship between electric and magnetic fields, electromagnetic induction, and Maxwell’s equations.
