Microstructure and electrical conductivity of plasma deposited gold/fluorocarbon composite films

摘要: Gold containing plasma polymerized fluorocarbon films have been deposited at room temperature by reactive rf sputtering. The dc electrical conductivity of the has measured as a function gold volume fraction and changes drastically after annealing about 180 °C. Two phenomena can be distinguished: (1) contraction cross‐linked polymer phase in film due to internal relaxations which results relative increase fraction; (2) change cluster sizes shapes observed transmission electron microscopy (TEM). latter effect is best interpreted using effective medium theory Sheng accounts for influence particle shape on percolation threshold variation composite material. Before annealing, described statistical mixture spherical coated with very flat platelets (oblate spheroids) gold, randomly oriented. ann...
