Description The operation of modern semiconductor devices is underpinned by a good knowledge of the physics of solid-state materials and electronics. This module is motivated by the need to link physical models with modern device operation. It uses basic quantum mechanical principles to explain the properties of materials of interest in electronic engineering practice. Knowledge of atomic bonding is essential for understanding how solids behave and why their electronic properties differ, distinguishing conductors, semiconductors and insulators. These material properties directly influence the performance of electronic components, shaping the operation of current and emerging technologies. Building on this foundation of solid-state physics the module introduces the student to the basic parameters which control the behaviour of electronic devices, such as diodes, transistors, MOSFETs, and solar cells. | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
