COURSE AIMS

The main aim of this course is to further correlate the structure of materials to their electrical, thermal, optical and magnetic properties. The course will highlight the importance of careful design of the materials structure to harness the associated properties in real application examples. Understanding of these relationships helps you to achieve different functional properties in a given materials combination/system for a specific application that is necessary for a materials engineer.

INTENDED LEARNING OUTCOMES

By the end of this course, you (as a student) would be able to:

  1. Explain the electrical properties of materials based on band theory .
  2. Apply calculations to determine the electrical conductivity of metals and semiconductors.
  3. Evaluate BH curves of magnetic materials.
  4. Determine the thermal properties of materials based on their density, bond strength and types of bond.
  5. Determine optical properties of solid materials based on the materials classes, crystal structures and bonds .
  6. Evaluate the link between materials structure and their associated properties.
