NANO8701 Structure and Characterisation GE

This topic deals with the fundamentals of fabrication and characterisation of two-dimensional structures at the nanscale. 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

This topic aims 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
• Introduce students to more advanced theory of instrumental techniques and how these are used to characterise particular types of nanomaterials and structures

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 the ability to develop 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
