Further information on descriptions Description: Aims:
The aims of this unit are to introduce areas of condensed matter physics that extend beyond the conventional domain of regular, infinite, crystalline solids.

Learning Outcomes:
After taking this unit the student should be able to:
* relate the electronic, optical and mechanical properties of real crystals to their defects;
* make quantitative estimates of the parameters that govern the behaviour of real solids;
* describe the structure and properties of amorphous solids;
* describe, compare and contrast experimental probes of solid surfaces;
* describe the structure, phase behaviour, and diffusive properties of polymers, colloids and liquid crystals;
* describe the principal structural and relaxational properties of solid, liquid, and soft matter glasses in terms of simple models.

Numeracy T/F A, Problem Solving T/F A.

Real solids (3 hours): Defects in crystals; point defects and dislocations in crystals. Effect on electronic, optical and mechanical properties. Point defects in thermal equilibrium. Self diffusion. Ionic conductivity. Colour centres.
Surface physics (6 hours): Clean and real surfaces, UHV, epitaxial growth. Surface energy; nearest neighbour bond model. Surface nets and unit meshes, reconstructions, adsorbates, the work function. Auger, UV and X-ray photoelectron spectroscopy. Reciprocal nets and diffraction. LEED, the scanning tunnelling and atomic force microscopes.
Introduction to amorphous solids (3 hours): Topological disorder. Determination of glass structure. Short range order, vibrational states and thermal conductivity of glasses.
Soft condensed matter (10 hours): Introduction and overview: Characteristic features, sedimentation, Brownian motion and random walks. Colloids: Diffusion, the Stokes-Einstein relation. Interacting colloid particles: phase behaviour, crystals and glasses. Polymers: Chemical structure, models for the conformations of polymers - freely-jointed chain, freely-rotating chain, excluded volume effects. Concentrated polymer solutions.
