At the MESA+ Institute for Nanotechnology, University of Twente, we use the Linseis LSR-3
Seebeck Coefficient & Electric Resistivity measurement system intensively as part of the
research in the Inorganic Materials Science group on "Efficient energy harvesting by
nanostructured thermoelectric materials", supervised by dr. Mark Huijben. Oxide and silicide
compounds are being studied as they have great potential for thermoelectric applications.

In the last year various oxide and silicide thin films have been investigated to determine the
effect of controlled layer growth on the enhancement of thermoelectric behavior. It is known that
the incorporation of nanostructures can lead to a dramatic improvement of the thermoelectric
properties. The dependence of the structural, electrical and thermal properties on the growth
process is studied up to high temperatures in the Linseis LSR-3 system, which enables us to
provide a helium, oxygen or mixture background gas for optimal characterization. Variations in
the grains and grain boundaries of the layer on the nanometer length scale are expected to have
a strong effect on the thermoelectric properties. The obtain information will extend the current
limited knowledge about charge carrier transport and phonon scattering in oxide and silicide
materials and it will provide means to improve the efficiency and quality of nanostructured
thermoelectric materials for future thermoelectric device applications.
