Abstract
Abstract In this paper, simple chemical solution deposition method is used to prepare La0.95Sr0.05CoO3 thin films on SrTiO3 (001) substrates by acetate-based precursors. The derived film is characterized by x-ray diffraction, field-emission scanning electron microscopy and transmission electronic microscopy. The derived film is epitaxial growth with [100] La0.95Sr0.05CoO3|| [100] SrTiO3, indicating that the chemical solution deposition is an effective route to obtain the cobalt-based films. The resistivity, Seebeck coefficient and thermal power factor are 0.05Ω cm, 250 μV/K and 0.21 mWK− 2m− 1 at 300 K, respectively, which is higher than these of the ceramics, indicating epitaxial thin film is an effective route to enhance the thermoelectric properties of La0.95Sr0.05CoO3.
