Topic description
This topic deals with the fundamentals of fabrication and characterisation of two-dimensional structures at the nanoscale. Two approaches of fabrication are discussed, namely the 'top-down' approach and the 'bottom-up' approach. Topics covered will include:

  1. Issues of scale in relation to nanotechnology
  2. Contact angles and surface tension
  3. Film growth and vacuum science
  4. Physical vapour deposition (PVD), chemical vapour deposition (CVD) and atomic layer deposition (ALD)
  5. Superlattices/quantum wells
  6. Carbon nanotubes/graphene fabrication and applications
  7. Self-assembly
  8. Patterning and lithography
  9. Molecular imprinting methodologies and applications
  10. Ellipsometry/ Quartz crystal microbalance
  11. Atomic force microscopy (AFM) and scanning microscopes
  12. Scanning tunnelling microscopy (SEM)/Scanning electron microscopy (SEM)/ transmission electron microscopy (TEM)
  13. Surface Fourier Transform Infrared (FTIR) spectroscopy
  14. Confocal Raman imaging
Educational aims
The aim of this topic is to introduce students to the techniques of making and characterising two-dimensional structures on the nanoscale and help them appreciate the special properties and novel nanoscopic phenomena that these structures might have. The topic also introduces students to theories of more advanced instrumental techniques and how these are used to characterise particular types of nanomaterials and structures.
Expected learning outcomes
At the completion of this topic, students are expected to be able to:

  1. Understand changes in surface properties as decrease size of structures
  2. Understand how to fabricate two-dimensional structures at the nanoscale
  3. Understand various approaches required make patterned surfaces using both chemical and biological methods
  4. Understand cutting-edge methods used to characterise both patterned and non-patterned two-dimensional structures
  5. Have developed hands-on laboratory skills
  6. Have an awareness of laboratory practice and the sensitivity of nanoscale structures
  7. Have effective oral, written and interpersonal communicators to a wide range of audiences
  8. Appreciate the value of research and the pursuit of ongoing professional development
