| Learning Outcomes |
By the end of the module students will be expected to be able to:
- explain the origin of atomic and molecular energy levels;
- recognise the limitations of models describing molecular energy levels;
- relate experimentally observed phenomena to the properties of molecules;
- contrast experimental techniques use to produce and measure single molecule devices;
- discuss commonly used electronic molecules, polymers and films and their properties;
- classify liquid crystal materials and illustrate their applications;
- explain charge transport in molecular/polymer films and how it can be measured;
- discuss key molecular and polymer devices and explain their operation;
- critically assess the development and progress of molecular electronics.
