Electric, ferroelectric and photoelectric properties of Pb(Zr,Ti)O3-Nb:SrTiO3 junctions
The electric, ferroelectric and photoelectric properties of Pb(Zr,Ti)O3-Nb:SrTiO3 (PZT-STON) junctions were investigated on a broad range of temperatures. It was found that the hysteresis loop is strongly asymmetric, due to the asymmetry in the leakage current. The capacitance-voltage characteristic has a butterfly shape although it is also asymmetric because of the different nucleation and compensation conditions at the two interfaces. The junction shows a strong photovoltaic effect in the 200- 500 nm wavelength range as short-circuit currents of the order of nA for an illuminated surface of 0.018 mm2. This makes the PZT-STON junctions attractive for UV optoelectronic applications.
