Abstract
A thermal phase transition has been resolved in gold nanoparticles supported on a surface. By use of asynchronous optical sampling with coupled femtosecond oscillators, the Lamb vibrational modes could be resolved as a function of annealing temperature. At a temperature of 104 °C the damping rate and phase changes abruptly, indicating a structural transition in the particle, which is explained as the onset of surface melting.
