Leader: B C Muddle
Offered:
Clayton Second semester 2005 (Day)
Synopsis: The subject will focus on the 'smart' functional roles of the materials in devices which depend on their electrical, optical and thermal properties. Examples of such devices are: active semiconducting devices and associated passive electrical components, 'smart' transducers, optical fibres, optical coatings, liquid crystal displays, optical storage devices, the ruby laser, the solar cell, ceramic insulators, the Peltier cooler. The functional materials will be studied at the microscopic (atomic and/or molecular) level in order to gain an understanding of the device operation. In addition, some discussion will focus on device fabrication.
Objectives: On successful completion of this course students will be able to: 1. understand the atomic and molecular structures of functional electrical materials 2. describe conduction processes in metals, alloys, semiconductors, polymers and ceramics 3. understand the temperature dependencies of these processes to the extent that they relate to the functioning of modern devices 4. understand the microscopic origins of polarization processes in electrical insulators, ionic, molecular, ferroelectric and piezoelectric materials 5. account for optical transmission and absorption processes in polarizable electrical materials 6. appreciate material compatibility requirements in the fabrication of devices from different classes of materials 7. conduct laboratory experiments designed to measure properties and to have an appreciation of the importance of experimental accuracy in measuring physical properties 8. appreciate the importance of a co-operative team effort in materials evaluation 9. prepare and present written reports on property measurement 10. appreciate the role of physical property assessment in materials research and/or manufacturing.
Assessment: Four written assignments (10%), laboratory work (30%), one x 3-hour written examination (60%).
Contact Hours: Three 1-hour lecture/practice classes and one 3-hour laboratory class per week
