Requisites

Prerequisite

Aims

The unit aims to:
1. provide an understanding of the principles underlying the operation of oxide-based functional ceramics in the form of bulk, thin film, particulate and composite materials;
2. discuss the relationships between chemical composition, crystal structure, microstructure and functional properties; and
3. identify the material characteristics required for a variety of applications and environments.
 

Overview

Functional materials are at the heart of a wide range of consumer and industrial electronic systems, including communications, control and energy management

Teaching and learning methods

Lectures, recommended textbooks, past exam papers, coursework/tutorials, electronic supporting information (Blackboard)

Learning outcomes

A greater depth of the learning outcomes will be covered in the follwing sections:

  • Knowledge and understanding
  • Intellectual skills
  • Practical skills
  • Transferable skills and personal qualities

Knowledge and understanding

• Demonstrate an understanding of the composition-structure-property relationships in polycrystalline ferroelectrics.
• Describe the main groups of conventional piezoelectric and pyroelectric ceramics; identify emerging single phase and composite materials and their characteristic properties.
• Explain how structural phase transformations in ferroelectrics can be exploited in the development of new and improved materials.
• Describe the mechanisms of operation and the processes of conduction in voltage dependent resistors and temperature-sensitive resistors.
• Describe the factors controlling the dielectric properties of high frequency dielectrics and their dependence on processing conditions.
• Explain the detection mechanisms in semiconducting gas sensors and identify factors limiting their performance.
• Describe the principles of operation of solar cells and fuel cells, and discuss factors limiting their performance.
• Describe the structure, production routes and applications of 1D and 2D nanomaterials.
• Discuss the electronic and other physical properties of a range of 1D and 2D materials.
• Relate the band structure of graphene to its electronic properties.
 

Intellectual skills

• Devise strategies to optimise the performance of functional materials.
• Relate the properties of functional materials to their structures and hence identify suitable applications for them
