Effect of Substrate Temperature on the Properties of Vacuum Evaporated Thin InSb Films

Abstract

Thermal environment of the mud is oneof the major parts of the acid-contaminatedgeo-environment of the Ariake Sea. The activitiesof marine ecosystem both in tidal flats and insidethe deep sea mud depend strongly on the thermalenvironment. In order to investigate the thermalproperties of the Ariake sea mud, a portablethermal properties sensor and probe (KD2,Decagon Devices, Inc.) was used. Thermalconductivity, thermal resistivity, thermal diffusivityand volumetric heat capacity of the mud samplescollected from both the tidal flat and inside thedeep sea were measured. The thermal propertiesof mud collected from tidal flat showed adifferent trend from the mud collected frominside the sea due to the enough exposure to thesunlight and vigorous exchange of sea water inthe tidal flat in different depths. Thermalconductivity of the Ariake mud was reduced85-90% after it was oven dried and was increasedup to 30% after the ignition loss test. Thermalresistivity of the Ariake mud increaseddramatically after oven dried and it was lessaffected by the organic matter content. Thermaldiffusivity was decreased 10-30% after oven dryhowever it was increased up to 40% after theignition loss test. The volumetric heat capacityof the Ariake mud was reduced up to 90% and40% after the oven dry and ignition loss,respectively.
