Title: Ferroelectric Pb(Zr,Ti)O{sub 3} epitaxial layers on GaAs

Ferroelectric epitaxial Pb(Zr,Ti)O{sub 3} (PZT) layers were grown by pulsed laser deposition on SrTiO{sub 3}/GaAs templates fabricated by molecular beam epitaxy. The templates present an excellent structural quality and the SrTiO{sub 3}/GaAs is abrupt at the atomic scale. The PZT layers contain a- and c-domains, as shown by X-Ray diffraction analyses. Piezoforce microscopy experiments and macroscopic electrical characterizations indicate that PZT is ferroelectric. A relative dielectric permittivity of 164 is extracted from these measurements.
