Abstract
A complementary metal-oxide-semico-nductor (CMOS)-compatible method for the direct fabrication of arbitrary-shaped Pb(Zr0.52 Ti0.48)O3 and PbTiO3 ferroelectric/piezoelectric nanostructures on plastic, silicon, and soda-lime glass substrates is reported. Thermochemical nanolithography is used to induce nanoscale crystallization of sol-gel precursor films. Ferroelectric lines with width ≥30 nm, spheres with diameter ≥10 nm, and densities up to 213 Gb in(-2) are produced.
