Abstract in another language

The aerosol deposition (AD) is a novel coating process to obtain dense ceramic coatings at high deposition rates (several μm/min) directly from the raw material. This technology bases upon a room temperature impact consolidation process (RTIC) to deposit ceramic materials on various substrates without using a high temperature step during the coating process. Thus a broad spectrum of temperature sensitive substrates or applications can be accessed when processing thermoelectrics.
In this contribution a first feasibility study was conducted by coating the reference thermo-electrics Bi2Te3 and CoSb3 on alumina substrates. The resulting films exhibit a homogenous thickness up to 100 μm and the thermoelectric properties (Seebeck coefficient and electrical conductivity) were measured simultaneously by a novel measurement transducer for thin thermoelectric films. Hence the Power-Factor of aerosol deposited Bi2Te3 and CoSb3 could be determined.
