Abstract

Comparison has been made between the microstructures and electrical properties of Pb0-95 La0.05TiO3 (PLT) thin films deposited on bare (100)MgO and on Pt/(100)MgO, Nearly perfect epitaxial PLT was grown on (lOO)MgO. (100)-oriented Pt film was obtained via coalescence of Pt islands formed on MgO. Highly c-axis oriented PLT thin film was successfully grown on the Pt bottom electrode with an electrically conductive network structure. High detectivity of 3.5 x 108 and 2.6 x 108 cm/Hz/W was obtained at 30 Hz without any poling treatments from the PLT/MgO-and PLT/Pt/MgO-based infrared detectors, respectively.
