Quasicrystals are intermetallic alloys which have long-range order without periodicity and hence display unusual rotational symmetries. In this talk I will discuss their surfaces as templates for building novel nanostructures and thin films and the role they can play in exploring the physical consequences of aperiodicity. I will also describe an ongoing debate on the stability of clusters in these materials as revealed in fracture studies and crack-propagation modelling.

This talk is part of the Surfaces, Microstructure and Fracture Group series.
