Ionic conductivity of (111) AgBr thin films, evaporated onto mica substrates in an oil-free vacuum system, was separated into bulk and surface components and the activation energies for these two components of the film-conductance were determined to be 0.50 eV and 0.42 eV, respectively. The relative contributions of the bulk and surface components to the ionic conduction process were also studied. The results found in this work are in agreement with the results and predictions of previous works. Preliminary attempts were also made to separate the bulk and surface components of the conductance after the application of a cationic dye. More work is needed in this latter area to obtain meaningful results.
