Thermal and Transport Properties of Granular Metal Thin Films

Abstract

The objectives of our research program have been to carry out a systematic experimental and theoretical study of the thermal and transport properties of granular metal films. This work has involved the preparation of a number of different granular metal systems by RF sputter deposition, characterization of these materials by x-ray diffraction (XRD), transmission electron microscopy (TEM), and x-ray photoelectron spectroscopy (XPS), the study of thermal properties by differential scanning calorimetry (DSC) measurements, and the study of the electrical transport behavior from room temperature to below 100 mK and, at low temperatures, in applied magnetic fields up to about 6 T. Using a variety of complementary analytical and numerical techniques, detailed theoretical studies have also been carried out on the structure, melting, transport, and optical properties of small granular particles.
