Department/Abbreviation: SLO/BNNE

Year: 2021

Guarantee: 'doc. Mgr. Jan Soubusta, Ph.D.'

Annotation: Brief introduction to nanophotonics, describing phenomena at the interface of solid state physics and optics. The lecture presents techniques of microscopy in near field and scanning probe microscopes. Next energetic conversion in nanostructures and utilization of nanostructures properties for efficiency increase is explained.

Course review:
- Basics of nanophotonics, spatial confinement: similarities and differences between photons and electrons, localization, tunneling. Interaction with nanostructures for photons (evanescent waves, plasma resonance) and for electrons (quantum mechanical size effect, Coulomb blockade). Overview of usage of mentioned phenomena in present and future components for optoelectronics - Photospectroscopy, overview of optical methods for studying nanostructures. Description of different methods of photoluminescence measurement utilizing microscopy and time resolution. - Near field scanning microscopy. Diffraction limit and optical system resolution. Principle of operation based on evanescent waves. Practical demonstration using scanning probe. Usage for the study of nanostructures. Principles of operation of scanning probe microscopy, study of spectroscopic properties of individual molecules. - Scanning tip microscopes, scanning tunneling microscopy (STM) and atomic force microscopy (AFM), modification of AFM with the use of other interactions: work function, electrostatic force, magnetic force, measurement with local detection of electric current of capacity - Energy transformation in nanostructures, basics of photovoltaic phenomenon in classical solar cells, effect limiting the efficiency of photovoltaic transformation, usage of properties of nanostructures for the increase of the efficiency: multiplication of carriers, photon fusion, multiple generation of charge carriers. Basics of photoelectrochemical cells: a dye-sensitized solar cells, photoelectrochemical decomposition of water.
