Vsebina:
Content (Syllabus outline):

Aktualne tehnološke rešitve in metode za merjenje lokalnih električnih, elektromehanskih in termičnih lastnosti funkcijskih materialov.

Osnovni principi delovanja mikroskopa na atomsko silo (AFM) s piezoelektričnim (PFM), prevodnim (CAFM) in temperaturnim (SThM) modulom ter ostale sorodne tehnike.

Napredne merilne tehnike na osnovi AFM, kot na primer tehnika za določanje lokalnih elektrokaloričnih lastnosti na osnovi modificiranega SThM sistema.

Povezave med lokalnimi in makroskopskimi lastnostmi funkcijskih materialov.

Individualno poglobljena analiza izbranega realnega primera iz študentove disertacije:
I) izbor primerne tehnike za določitev želenih lokalnih lastnosti (kot na primer lokalne električne prevodnosti, lokalnega piezoelektričnega odziva, feroelektrične domenske strukture, nukleacija in preklaplanje domen, lokalna toplotna prevodnost, itd.),
II) eksperimentalno delo na mikroskopu ter analiza dobljenih rezultatov.

Up-to-date technological solutions and methods for determination of local electrical, electromechanical and thermal properties of functional materials.

Basic principles of atomic force microscopy (AFM), piezo-force microscopy (PFM), conductive-force microscopy (CAFM), scanning thermal microscopy (SThM) and related techniques.

Advanced measurement techniques based on AFM, such as determination of local electrocaloric properties by modified SThM system.

Connections between the local and macroscopic properties of the functional materials.

Individual analysis of a case study related to the topic of the student’s PhD research:
I) selection of a suitable technique for the determination of local target properties (such as local electrical conduction, local piezoelectric response, ferroelectric domain structure, domain nucleation and switching, local thermal conductivity, etc.),
II) practical work on the microscope and analysis of measured results.
