Abstract
Perovskite oxides (ABO3) are extensively used in photovoltaics, optoelectronics, gas sensors, RRAM devices, etc. because of their easy scalable fabrication and tunable properties. Lanthanum doped Barium Stannate Oxide (La: BaSnO3) is a transition metal oxide (TMO) that remains stable up to 1000 °C has a cubic perovskite structure and possesses n-type semiconductor behavior with a wide band gap (Eg ≥ 3 eV). Moreover, it is one of the few transparent conducting perovskite oxides (TCO). In the present study, La-doped BaSnO3(La0.05Ba0.95SnO3) bulk and films having cubic perovskite structure were synthesized by solid-state reaction route and Pulse Laser Deposition (PLD) technique on sapphire (0001) substrate, respectively. Effects of deposition rate during the experiment on structural properties were investigated by X-ray diffraction. Morphological study of films was done by atomic force microscopy and optical properties were done using UV–vis spectroscopy respectively. We present the growth mechanism and structural and surface properties of La0.05Ba0.95SnO3 in detail.
