Indium tin oxide (ITO) and fluorine tin oxide (FTO) are the subset of the larger transparent conducting oxide family and possess transmittance in the visible spectrum as well as high electrical conductivity. Even though their unique optical and electrical properties have been thoroughly examined, the thermal transport properties, namely, thermal conductivity in the cross-plane direction, have received much less attention. In this paper, using a series of ITO and FTO thin films comprising a range of thicknesses and grain sizes, we characterize the cross-plane thermal conductivity using time-domain thermoreflectance. We determine the heat capacity of the FTO films from simultaneous measurements of volumetric heat capacity and thermal conductivity on an 396-nm-thick FTO film. We show that the size effects have a considerable influence on the thermal conductivity from both the perspective of grain boundary and thin film scattering.Pages 51-577 page(s)application/pdfenIn CopyrightScience & TechnologyTechnologyEngineering, ManufacturingEngineering, Electrical & ElectronicMaterials Science, MultidisciplinaryEngineeringMaterials ScienceFluorine tin oxide (FTO)heat capacityindium tin oxide (ITO)thermal conductivitythin filmtime-domain thermoreflectance (TDTR)transparent conducting oxide (TCO)CONJUGATED POLYMER SURFACESOPTICAL-PROPERTIESITO FILMSTEMPERATUREINTERFACESELECTRODE40 Engineering4016 Materials Engineering4009 Electronics, sensors and digital hardware4014 Manufacturing engineeringArticlehttps://doi.org/10.1109/TCPMT.2018.286364891Rost, Christina [0000-0002-6153-6066]2156-3985
