نویسندگان
چکیده
Thin-film Ni–Ca3Co4O9 and Ni–Mo thermocouples were prepared by stepwise magnetron-sputtering/annealing synthesis using masks. Compared with thin film thermocouples, have higher output voltage due to large positive Seebeck (153 ?V/K for single thermocouple 912 6-series thermocouple). The maximum from the is 70 mV was obtained a hot-end temperature of 105 °C thermocouple. stability Ca3Co4O9 films ability make free-standing films, together high coefficient, show that these thin-film oxides can be used as p-type leg in implications use flexible thermoelectric devices.

Microstructure Evolution and Thermoelectric Property of Pt-PtRh Thin Film Thermocouples
Due to their small size, extremely fast response, and low cost, refractory metallic thin film thermocouples (TFTCs) are well suited for the surface temperature measurement of hot components. In this study, PtRh films with different amounts of Rhodium (10% and 13%) were deposited with direct current magnetron sputtering and annealed at different temperatures in air. The chemistry, microstructure...
متن کاملNanostructural Tailoring to Induce Flexibility in Thermoelectric Ca3Co4O9 Thin Films
Because of their inherent rigidity and brittleness, inorganic materials have seen limited use in flexible thermoelectric applications. On the other hand, for high output power density and stability, the use of inorganic materials is required. Here, we demonstrate a concept of fully inorganic flexible thermoelectric thin films with Ca3Co4O9-on-mica. Ca3Co4O9 is promising not only because of its ...
متن کاملMixed thick/thin-film thermocouples for thermoelectric microgenerators and laser power sensor
This work presents the fabrication of thermopiles with high output voltage. A series of mixed thick/thin-film thermopiles were performed – one of the arms of the thermocouples was screen-printed (PdAgor Ag-based thick-film layers), the second was made of magnetron sputtered semiconductor (compositions based on Ge). The output parameters (thermoelectric force ET [V], internal resistance Ri [Ω], ...
متن کاملLocal structure of thermoelectric Ca3Co4O9
We have combined temperature-dependent local structural measurements with first-principles densityfunctional calculations to develop a three-dimensional local structure model of the misfit system Ca2CoO3 CoO2 1.61 referred to as Ca3Co4O9 which has a rocksalt structure stacked incommensurately on a hexagonal CoO2 lattice. The local structural measurements reveal a low coordination of Co 2 -O bon...
