Overview
  • The new field of 2-dimensional (2-d) materials has seenexponential growth since the isolation of graphene, a single atomic layer ofcarbon atoms, at University of Manchester in 2004. What is a 2-d material, andhow is it different to 3-dimensional materials that we encounter every day? Howdoes the 2-d nature affect the material’s properties, for instance, how doelectrons living in a 2-d world behave? How would we harness the uniqueproperties of 2-d materials and put them to use in real-world applications? Wewill answer these questions and more in this course on Graphene and other 2-dmaterials.

    The course will describe how a number of keyaspects of the broader field of nanomaterials are applied to study 2-dmaterials, including methods of production such as chemical vapour deposition,characterisation techniques such as Raman spectroscopy and electron microscopy,and the production of nano-electronic and nano-composite structures.
