            - Additional extrinsic effects (Hall & Seebeck/Peltier effect)

  • Modern Model of Solids

            - Band theory of solids (electrons and holes in periodic potentials)

            - Effective mass and density of states

            - Fermi energy, ionisation potential and work function

  • Semiconductors

            - Energy diagrams in k-space (direct and indirect bandgaps) 

            - Conduction in semiconductors (electron/hole populations) 

            - Intrinsic/Extrinsic semiconductors (n-, p-type, compensation doping) 

            - Temperature & impurity dependence of conductivity (drift mobility) 

  • Semiconductor Devices

Aims

This course unit detail provides the framework for delivery in 2020/21 and may be subject to change due to any additional Covid-19 impact.  Please see Blackboard / course unit related emails for any further updates.

The course unit aims to:

  • Introduce nanotechnology and its importance in today’s society (e.g. applications in healthcare, security, and energy)
  • Introduce basic materials physics and explain how insulating, semiconducting and metallic properties arise in solids.
  • Explain how semiconductors can be engineered (e.g. via doping) to exhibit controlled electrical and optical properties within a device.
  • Describe the fundamental building blocks and operation of key semiconductor devices (e.g. field effect transistors)
