Vsebina:

Content (Syllabus outline):

Smernice razvoja okolju prijazne piezoelektrične keramike.

Sintezne metode okolju prijazne piezoelektrične keramike s poudarkom na sintezi materialov na osnovi alkalijskih niobatov in bizmutovega ferita (volumenska keramika, debele in tanke plasti, monokristali).
Kritični parametri sinteze, ki vplivajo na funkcionalne lastnosti študiranih materialov.

Novejše metode za strukturno, mikrostrukturno, električno, elektro-mehansko karakterizacijo okolju prijaznih piezoelektričnih materialov (od lokalnih do makroskopskih odzivov).

Individualno poglobljena analiza izbranega realnega primera iz študentove disertacije: izbor primerne metode sinteze materiala in ustreznih metod karakterizacije.

Development trends in environmentally -friendly piezoelectric materials.

Synthesis methods of environmentally-friendly piezoelectric materials based on alkaline niobates and bismuth ferrite (bulk, thick films, thin films and single crystals).
Critical synthesis parameters which influence the functional properties of the studied materials.

Advanced methods for structural, microstructural, electrical, electro-mechanical characterization of environmentally -friendly piezoelectric materials (from local to macroscopic responses).

Individual analysis of a case study related to the topic of the student’s PhD research: selection of a suitable synthesis method of the studied material, and characterization methods.
