Course Description

Local electrical, electromechanical and thermal properties of the sensor materials

Program

Sensor Technologies

Lecturers:

doc. dr. Hana Uršič Nemevšek

Goals:

The objectives of the course are:
• student becomes familiar with the concepts of and equipment for determination of local electrical, electromechanical and thermal properties of different sensor materials.
• student understands basic principles of AFM, PFM, CAFM, SThM and other related techniques such as Kelvin-probe force microscopy (KPFM), electrostatic-force microscopy (EFM) and magnetic-force microscopy (MFM)
• student measures and analyses selected material´s characteristics (a short research project).

Competences of the student:
• Ability to select appropriate technique for desired local measurements.
• Ability to prepare the samples (for example crystals, bulk materials, thin and thick films, nanomaterials, etc.) for microscopic analyses of local properties.
• Ability to determine and analyse selected material´s characteristics such as local electrical conduction, local piezoelectric behaviour, ferroelectric domain structure, local thermal properties, etc.
• Ability to understand the connections between the local and macroscopic properties of materials.

Content:

• 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.

Course literature:

Targeted selection of papers from Nature, Science, Advanced Functional Materials, Sensors and Actuators, Physical Review Letters, Acta Materialia.
