Thin films have potential to surpass bulk materials with a similar composition in terms of thermoelectric properties because of much lower thermal conductivity. This idea was followed in the investigations on magnetron sputtered Cu-Se films. Targets with a desired Cu:Se atomic ratio close to 2:1 were produced by melting and solidification in the evacuated quartz ampoules, grinding into powders, hot pressing and machining. Thin films were deposited on glass substrates or on silicon wafers. Doping trials of the baseline composition were executed by means of an additional target installed in the experimental set-up. Morphology, chemical composition and phase composition of the films were routinely characterized by SEM/TEM, EDS and XRD. Thermoelectric properties were evaluated by means of LINSEIS Thin Film Analyzer which enables simultaneous determination of all crucial physical parameters on one sample during one measurement run.
