| Aims: | The aims of this unit are to outline properties of materials at the nanoscale, to describe methods for the fabrication, visualisation and probing of nanostructures, to introduce topical low-dimensional nanomaterials and novel physical concepts related to them, and to give some examples of their possible applications. |
| Skills: | Numeracy T/F A, Problem Solving T/F A. |
| Content: | Nanoscience and nanotechnology - what are they and how did they arise? (6 hours):
Glass science (5 hours): The glassy state, glass transition, entropy crisis, Kauzmann Paradox, viscosity in glass forming liquids, rigidity, constraint counting theory, glass structure. Probing and manipulation at the nanoscale - The Lab on a Tip (4 hours): 1. Principles of Scanning Tunnelling Microscopy (STM): Imaging & spectroscopy, manipulation of atoms and molecules. Relationship to electronic structure. Spin-related phenomena. Inelastic tunnelling. 2. Principles of Atomic Force Microscopy (AFM): Forces at the nanoscale and AFM modes. Application in material/life sciences. (e.g. chemical, electrical, magnetic properties, self-assembly). Atomically-resolved imaging and probing (e.g. conformation of molecules on surfaces; interaction of two-dimensional materials with substrates). Quantum phenomena at the atomic scale (1 hour): Electron scattering & confinement: Quantum Corrals; Quantum Interference. Molecular "graphene": designer Fermions. Low-dimensional nanomaterials (6 hours): 1. Carbon-based nanomaterials: Bonding and carbon allotropes. Graphene (Dirac cones and linear energy bands; From graphene to graphite; Klein tunnelling; Pseudospin; Engineering electronic properties: graphene in an external potential). Confinement effects: graphene nanoribbons and carbon nanotubes. 2. Other (non-carbon) 2D nanomaterials: Transition Metal Dichalcogenides (types, transition from bulk to monolayer, basic properties). Silicene: a graphene-like monolayer of silicon. Comparison with graphene. |
