Investigation of photoelectric properties of CuO / PZT heterostructures in the visible and near IR regions

Abstract

Abstract The method of formation of copper oxide / lead zirconate titanate (CuO/PZT) heterostructures using RF magnetron sputtering of chemically pure grade copper oxide powder on prepolarized ferroelectric ceramic substrate is considered; the direction of polarization was parallel with the copper oxide film plane. The short-circuit photocurrent in the CuO/PZT samples with different thicknesses under irradiation in the visible and near IR regions was measured. The spectral dependences of the photocurrent were estimated. The maximum photoresponse of the structures was observed at the wavelength of 515 nm.
