SUMMARY:Quasicrystals: there be monsters... - Professor Ronan McGrath\, Su
 rface Science Centre\, Department of Physics\, The University of Liverpool

CONTACT:Stephen Walley
DESCRIPTION:Quasicrystals are intermetallic alloys which have long-range o
 rder without periodicity and hence display unusual rotational symmetries. 
 In this talk I will discuss their surfaces as templates  for building nove
 l nanostructures and thin films and the role they can play  in exploring t
 he physical consequences of aperiodicity. I will also describe an ongoing 
 debate on the stability of clusters in these materials as revealed in frac
 ture studies and crack-propagation modelling.
