Electron microscopy and spectroscopy of nanophotonic structures and materials
Řepa, Rostislav ; Paták, Aleš (oponent) ; Křápek, Vlastimil (vedoucí práce)
The lightning-rod effect is a well-established principle in electrostatics, characterized by the generation of a strong electric field near the pointed features of a charged conductor. In the field of plasmonics, the influence of local curvature on the induced electric field around metal nanoparticles (plasmonic antennas) is similarly observed. Besides this socalled plasmonic lightning rod effect, other phenomena such as the charge reservoir of the plasmonic antenna, the surface wave localization, and the interaction between two plasmonic antennas also contribute to field enhancement. This thesis utilizes electron energy loss spectroscopy and electromagnetic simulations to quantitatively examine these distinct phenomena by isolating their partial contributions to the strength of the induced electric field around a plasmonic antenna.
