ABSTRACT
Molybdenum doped (0–1 at. %) indium oxide thin films with high near infrared (NIR) transparency and carrier mobility were deposited on Corning-1737 glass substrates at 400 °C by spray pyrolysis experimental technique. Films with mobility as high as ∼149 cm2/V s were obtained when annealed in vacuum at 550 °C, which also possess carrier concentration of ∼1×1020 cm-3 and resistivity as low as ∼4.0×10-4 Ω cm. Further, both the average visible transmittance (500–800 nm) and the average NIR transmittance are >83%. This clearly shows that the transmittance is extended well into the NIR region.

    Transport properties of aliovalent-ion-doped BiFeO3 (BFO) thin films have been studied in order to identify the cause of high leakage currents. Doping of 2 at. % Ti4+ ions increased the dc resistivity by more than three orders of magnitude. In contrast, doping of 2+ ions such as Ni2+ reduced the...
