Abstract
- Conductive and transparent La<subscript>0.07</subscript>Sr<subscript>0.93</subscript>SnO<subscript>3</subscript> (LSSO) films were employed as electrodes for the fabrication of epitaxial Pb(Zr<subscript>0.52</subscript>Ti<subscript>0.48</subscript>)O<subscript>3</subscript> (PZT) ferroelectric capacitors. Due to a negligible lattice mismatch between LSSO and PZT, the LSSO/PZT/LSSO heterostructures grown on SrTiO<subscript>3</subscript>(001) substrates show excellent single-crystalline quality as revealed by high-resolution x-ray diffraction and are transparent with transmittance comparable to that of pure SrTiO<subscript>3</subscript>(001) substrates at the wavelength of 400–2500 nm. These capacitors show square polarization–electric field hysteresis loops but smaller polarization, larger coercive field, and especially poor fatigue resistance, in sharp contrast with those observed for the conventional epitaxial all-oxide PZT capacitors.
