The aim of this module is to provide theoretical and practical knowledge on the materials that underpin electronic devices. The indicative content for this module encompasses the solid-state physical macro- and nano-scale properties of solid conductor, insulator, semiconductor and optoelectronic materials that make them useful in electronic devices, their structures, the behaviour of electrons, electrical conduction, lattice vibration, thermal conduction, how dopants are used, and their interaction with light where appropriate. Existing electronic materials as well as future developments will be explored.
