January 2011The SEM picture shows an originally dense and covering thin silver layer, which was deposited by pulsed laser deposition (PLD) on top of an (111) oriented substrate of yttria stabilised zirconia (YSZ). In the picture the dewetted surface after annealing the sample at 400 °C for 1 hour in oxygen atmosphere is shown. Although silver has a melting point of 962°C, thin silver films are unstable even at moderate temperature, as silver shows an extremely high mobility. Picture submitted by C.
