ABSTRACT: Thermoelectric layers as Bi2Te3, Yb0.19Co4Sb12,
FeSb2Te, Ce0.1Fe0.7Co3.3Sb12 and FeSb2Te/Ce0.1Fe0.7Co3.3Sb12 multilayers were prepared
by Pulsed Laser Deposition (PLD). Smooth, nano-crystalline, stoichiometric layers
were synthetized in a classical PLD arrangement or in a special off-axis PLD arrangement,
followed by Rapid thermal annealing. Results of physical characterizations such
as morphology—Atomic Force Microscope, Scanning Electron Microscope, composition-Energy
Dispersive X-ray analysis, crystallinity—X-ray Diffraction, separation of multilayers—Secondary of ion
beam mass spectroscopy SIMS and study of thermoelectric properties such as the thermoelectric
figure of merit ZT, in-plane electrical resistivity, Seebeck coefficient and thermal
conductivity are presented. For thermal conductivity measurement a newly developed
Atomic force thermal microscope (AFMTh) was tested. Results obtained on the single
layers compared to multi-layered structures are discussed.
