After taking this module students should be able to:
understand the basic mechanisms of electrical conductivity in semiconductors.
understand the physics of interfaces.
understand the operation of the p-n junction and appreciate its crucial role in the production of integrated semiconductor devices.
production of integrated semiconductor devices.
understand the operation of MOS devices.
appreciate the future direction of semiconductor device technology.
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.
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.
JFET, MOSFET and MESFET.
Power semiconductor devices (thyristor structures, bipolar power transistors, MOS power transistors).
Semiconductor optoelectronic devices. Detectors (photodiodes and transistors, photovoltaic devices, CCDs) and emitters (LEDs, LCDs and lasers).
