Module summary

Comparison of conducting properties of metals, insulators and semiconductors. Conduction and valence band. Band gap. Electrons and holes. Carrier density & conductivity. Doping of semiconductors. Temperature dependence of semiconductors (compared to metals). Optical response of semiconductors. Metal/semiconductor junction & Schottky diode. pn junctions (simple treatment). Revision of wave propagation. Electromagnetic plane waves in free space. Wave polarisation. Relation between component size and EM wavelength Qualitative introduction to antennas. Circuit interference effects at high frequencies. Skin effect. Requirement for “signal carriers” designed for high frequency operation.

Objectives

Following on directly from Physical Electronics I (ELEC1900), this module provides a foundation of physical knowledge in the band theory of solids, how this leads to differences in conduction processes, and in the diodes which result from simple linear combinations of doped semiconductors and metals.

Learning outcomes
On completion of this module, students should be able to ...

- explain the differences in the conducting properties of insulators, semiconductors and metals in terms of electron energy bands,
- explain how the conductivity in semiconductors is affected by light and temperature, and how it can be engineered by adding controlled amounts of impurities;
- describe the materials structure and physical operating principles of basic diodes
- interpret the mathematical representation of a travelling wave
- appreciate the basic concept of an electromagnetic wave in free space
- appreciate the need to account for electromagnetic phenomena in high frequency circuit design
