ELEC2201 Devices

Module Overview

Semiconductor device technology has evolved beyond computation applications and is now increasingly being used in quantum electronics, lighting, lasers, high speed communications, photovoltaic energy harvesters, smart electronics for the Internet of Things, and sensing for healthcare and the environment. Semiconductor devices are not solely confined to silicon technology but include Group III-V compounds, such as gallium arsenide and indium gallium arsenide as well as other materials such silicon-germanium alloys, zinc oxide, molybdenum selenide and graphene. The next generation of semiconductor technologies will demand the knowledge and understanding to explore device platforms for new integrated circuit concepts and fabrication methods. ELEC2201 Devices will cover 3 main parts; (i) physical principles of the operation of semiconductor devices; (ii) semiconductor electronics and (iii) semiconductor optoelectronics. The module builds on ELEC1205 Solid States Devices, some parts of which will be revisited and so students should re-acquaint themselves with the theory of semiconductor materials including band energy diagrams, carrier concentrations and the concepts of doping and p-n junction formation. Throughout the course, undergraduates are encouraged to read beyond the lecture materials provided and the core text books.
