The principal aim of this topic is to understand science and technology governing the important properties and uses of electrical, optical and magnetic materials and development of associated nano-technological devices.

Quantum dots and quantum size effect, imaging techniques for nanostructures, organic transistors, single electron transistors, optical transmission and absorption processes in polarizable electrical materials, piezo and ferroelectric materials, superconducting materials and their applications.

Origins of magnetic moments, effects of magnetic field and temperature on magnetism, magnetic anisotropy, magnetostriction and effect of stress, magnetoresistance, technical magnetization process, magnetoelastic energy and domain wall, induced magnetic anisotropy, nanostructured magnetic materials, magnetization dynamic, application of nanostructured soft and hard magnetic materials, and magnetic materials for recording and computers, and devices based on nanomagnetism.

This topic aims to provide students with an understanding of the science and technology of fibre optics, ferroelectrics, piezo-and pyroelectricity and superconductivity. Students will understand the science and technology of hard and soft magnets, will learn to measure electrical and magnetic parameters, will be aware of some current areas of nano-device developments and their future possibilities, and some of the present techniques for examining nano-devices.

At the completion of this topic, students are expected to be able to:

1. Understand the science and technology of fibre optics, ferroelectrics, piezo-and pyroelectricity and superconductivity
2. Analyse electrical characteristics and magnetic properties of materials
3. Apply technical concepts involved in the use of electrical, optical and magnetic materials in relevant application
4. Understand nano-device developments and their future possibilities
5. Practise measurements of the electrical and magnetic properties of materials and have an appreciation of the importance of experimental accuracy in measuring physical properties
