Dielectric properties of materials

MSE-480

Lecturer(s) :

Damjanovic Dragan

Language:

English

Summary

Students learn about response of electrically insulating materials to electrical and mechanical fields. The emphasis is on effect of various types of defects on properties, on crystal structure/microstructure - property relations, and on ways how to engineer properties of materials for applications.

Content

Dielectric polarization. Dielectric relaxation in ceramics and polymers. Dielectric loss. Nonlinear dielectric properties. Hysteresis. Dielectric spectroscopy. Capacitors and insulators. Dielectric breakdown. Aging. Insulating materials for electronic packaging.

Piezoelectric effect. Polar dielectrics. Coupling of thermal, mechanical and electrical properties. Electrostriction. Ferroelectricity. Ferroelectric and ferroelastic domains. Piezoelectric ceramics and polymers. Composite materials. Piezoelectric resonance. Applications of piezoelectric materials: actuators, sensors and ultrasonic transducers. Medical application of piezoelectric materials. Environmentally friendly piezoelectric material; biocompatibility and functional materials.

Selected topics in multiferroic materials.

Pyroelectricity and pyroelectric materials and devices.

Thermistors. PTC and NTC effects.
