Metal/ferroelectric/superconductor field effect transistor using Pb(Zr0.52Ti0.48)O3/(Y0.6Pr0.4)Ba2Cu3O7-y heterostructures
Metal(Al,Ag,Au)/ferroelectric (Pb(Zr0.52Ti0.48)O3 [PZT])/high-Tc superconductor ((Y1-x Prx)Ba2Cu3O7-y [YPBCO]) structures have been fabricated by ArF excimer laser deposition. Ferroelectric properties of c-axis oriented epitaxial PZT films on YBa2Cu3O7-y[YBCO]//SrTiO33(100) have been studied as a function of temperature in the range of 20–290 K. Samples with three kinds of metal electrode show almost similar ferroelectric properties at 290K. The remanent polarization and coercive field are about 25μC/cm2 and 146 kV/cm, respectively. At low temperature, on the contrary, the ferroelectric properties of heterostructures were strongly influenced by the choice of the electrode metal. It seems that these properties are severely affected by interface states of metal PZT. The Au electrode gives rise to the best ferroelectric property of PZT films. We also investigated the ferroelectric field effect in the heterostructures of Au/ PZT/(Y0.6Pr0.4)Ba2Cu3O7-y. A large modulation (as much as ∼40%) and memory effects are observed in the low frequency source–drain current response to a pulsed voltage.
