Language of instruction
1. Introduction, the philosophy of modern physics and the physical nature of substances (moving atoms, molecules, clusters, etc.).
2. Special theory of relativity (Michelson-Morley experiment, Galileo and Lorentz transformation, Lorentz-FitzGerald contraction, time dilatation and other consequences).
3. Particle properties of waves (thermal radiation, quantum light theory, photoelectric effect, Compton effect, X-ray diffraction).
4. Wave properties of particles (duality principle, de Broglie wave, group and phase velocity, wave function, particle diffraction, uncertainty principle, John Wheeler's experiment).
5. Quantum mechanics (wave function, Schrödinger equation, Eigen values and functions, medium value operators, solution of the particle in the potential trap, Schrödinger's paradox).
6. Problems in quantum mechanics (degree of potential energy, harmonic oscillator, tunneling, resonant tunneling, quantum dot).
7. Quantum description of the hydrogen atom (SR for the hydrogen atom, quantum numbers, Zeeman effect, Stark effect, Bohr model).
8. Multi-electron atoms (electron configuration, Hund's rule, atomic spectra).
9. Energy states and energy band theories.
10. Interface (homogeneous and heterogeneous transitions in semiconductors, semiconductor-metal, semiconductor-insulator, Poisson equation, typical electron traps, state density).
11. Interface semiconductor-metal, semiconductor-insulator.
12. Nanoelectronics and charge transport (quantum conductivity, Coulomb Blocking and oscillation, Hall's phenomena).
13. Excursion to Thermo Fisher Scientific (FEI Czech Republic s.r.o.).
The target of the lecture is to present important phenomena of temporary Semiconductors interfaces and nanostructures with help of appropriate tools - Quantum and Statistical Physics.
