Abstract

The topography of indium tin oxide (ITO) films with incorporated

silver nanoparticles and irradiated by single pulses of 18 ns Nd:YAG

laser has been investigated. The study was carried out with two

Ag/ITO films having resistances of 50W/ITO sheet and 4W/ITO

sheet. The periodic structures in both samples were created after

the laser treatment. The photo-induced periodic structures have a

different character while the sheet resistance plays a major role

in the growth process of these structures. The results of optical

and non-linear optical investigations lead us to the conclusion that

the temporary polarization of samples during laser treatment is

responsible for the shape of periodic structures. This conclusion has

been also confirmed by local permittivity measurements using

evanescent microwave microscope.
