Synthesis and conductive properties of nanoisland Sn, Al, and Cu films

Nanoisland Sn, Al, and Cu films were synthesized on dielectric substrates and their morphology and conductive properties were investigated. It is shown that the initial effective film thickness significantly affects the morphological parameters of nanoislands. Study of the surface conductivity of the films at the condensation stage revealed the conductivity drop after termination of the deposition, which is related to the nanostructuring processes. It was found that the temperature dependences of the film conductivity include three portions: the low-temperature portion of the activation growth, the decrease upon nanostructuring, and the high-temperature portion of the activation growth.
