STRUCTURAL AND ELECTRICAL-PROPERTIES OF A METALLIC ROUGH-THIN-FILM SYSTEM DEPOSITED ON LIQUID SUBSTRATES

A rough-thin-him system, deposited on silicone oil drop surfaces by a rf-magnetron sputtering method, has been fabricated and its structure as well as I-V characteristics have been studied. A characteristic sur face morphology at the micrometer scale is observed. The anomalous dep osition rate, which strongly depends on the nominal film thickness, ca n be interpreted under the assumption of the second evaporating and th e penetrating effects. We find I-c proportional to R(0)(-alpha), with alpha=0.521-0.06, where R(0) and I-c are the zero power resistance and the breakdown current, respectively. The importance of the liquid sub strates is discussed.
