Brief description

This module provides a basic introduction to semiconductor physics, concentrating on those elements which underpin an understanding of the operation of semiconductor devices. The physics of important devices, such as bipolar and MOS transistors, will be detailed. In addition, an introduction to novel device structures which are being developed as a result of recent massive advances in semiconductor research will be provided.

Content

Semiconductor materials and their crystal structure - Miller indices.
Intrinsic and extrinsic conductivity. Shallow and deep centres.
Diffusion of carriers.
Junctions in semiconductor systems - the metal-semiconductor junction, homo- and hetero-semiconductor-semiconductor junction, and the metal-insulator-semiconductor junction.
The planar p-n and bipolar transistor structure. Planar resistor and capacitor structure.
