Abstract
Silver films formed on a cold sapphire substrate and studied prior to annealing exhibit a very different optical absorption from that typical of an annealed silver film. In particular a film formed and studied at 140 K showed a greatly reduced plasmon energy and a large anomalous absorption band centred at 2.4 eV. Annealing the film at RT caused a return to properties typical of an annealed film, although small but distinct differences remained between the Drude behaviour of the two films formed at different temperatures. The anomalous properties of the cold film are ascribed to structural disorder. The behaviour is analysed in terms of a two phase model.
