Short Abstract:
The objectives of this course are to:
- Introduce you to typical properties and uses of porous materials in general, and nanoporous silicon in particular
- Survey why the semiconductor silicon has been such an influential material, shaping modern society
- Demonstrate how nanostructuring a material can both radically change its properties and provide size-tunability of properties
- Talk about the challenges of nanotechnology, using nanoporous silicon examples, such as the need for more sustainable (“green”) synthesis and nanomaterial stability and cost
- Survey a broad range of applications being investigated for this nanomaterial from both a technical and commercial perspective
The course will particularly suit those students who have an interest in multidisciplinary science, nanotechnology and entrepreneurship.
