Course Description

Environmentally-Friendly Piezoelectric Ceramic Materials

Program

Ecotechnologies, third-level study programme

Lecturers:

doc. dr. Andreja Benčan Golob

Goals:

Objectives:
- understanding of principles of synthesis of environmentally-friendly piezoelectric materials
- knowledge of characterization methods for environmentally friendly piezoelectric materials
- understanding of critical chemical and physical properties of environmentally-friendly piezoelectric materials and their limitations
Competences:
-The student will master selected research methods, procedures and processes
-The student will develop critical thinking and self-assessment
-The student will develop communication skills to present research results in an international environment

Content:

-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.
