FeSb2 has a high potential for technological applications due to its colossal thermoelectric power, giant carrier mobility and large magnetoresistance. Earlier, growth of lang1 0 1rang-textured FeSb2 films on quartz (0 0 0 1) substrates has been reported. Here magnetron sputtering is used to obtain lang0 0 2rang-textured FeSb2 films by employing a pre-deposited FeSb2 thin-film layer as template. The in-plane thermoelectric properties of FeSb2 films with different orientations were studied and compared. The anisotropy of FeSb2 is shown to have an important effect on the transport properties of FeSb2 films. Orientation control of the FeSb2 films could be significant for their property optimization and thus highlight their application potential.
