Carrier manipulation in graphene/ferroelectric hybrid structures
… and characterization. The resulting graphene/PbZr0.2Ti0.8O3 hybrid structures presented here exhibit bidirectional interdependency between the graphene doping level and the ferroelectric polarization. Using graphene-based electrodes, the polarization of the PbZr0.2Ti0.8O3 can be switched …

Investigation of Ferroelectric Thin Film Using Piezoresponse Force Microscopy
… materials including tetragonal polycrystalline PbZr0.3Ti0.7O3 and epitaxial PbZr0.2Ti0.8O3 thin films were studied at different length scales using resonant PFM. This technique was also used to study the ferroelectric/ferroelastic domains and their dynamics. In the current work, the interplay …

Secondary pyroelectric and electrocaloric effects in thin films
… 15% and 20% of the total response for PbZr0.2Ti0.8O3 and Ba0.6Sr0.4TiO3 grown by PLD, respectively. By comparing the pyroelectric and electrocaloric coefficient measured on the same devices, our result shows the secondary contribution to the electrocaloric coefficient has the opposite …

Nanometer-thick oxide films for pyroelectric energy conversion
… and pyroelectric response in ~100 nm thick PbZr0.2Ti0.8O3 films deposited using pulsed laser deposition. Piezoresponse force microscopy (PFM), an atomic force microscopy (AFM) based technique, measured the electromechanical response while a doped-silicon resistive micro-heater provided local …

Orientation dependence of dielectric susceptibilities and switching characteristics in epitaxial ferroelectric thin films
… are used to elucidate the nature of switching in PbZr0.2Ti0.8O3 thin films. Differences are demonstrated between (001)-/(101)- and (111)-oriented films, with the latter exhibiting complex, nanotwinned ferroelectric domain structures with high densities of 90° domain walls and considerably …

Multiscale Simulations of Dynamics of Ferroelectric Domains
… of nanoscale ferroelectric domain structures in PbZr0.2Ti0.8O3 films. Molecular dynamics simulations predict both 180° for (001)-/(101)-oriented films and 90° multi-step switching for (111)-oriented films, and these processes are subsequently observed in stroboscopic piezoresponse force …
