Post-deposition control of ferroelastic stripe domains and internal electric field by thermal treatment

Nava Setter, Silviu Cosmin Sandu, Monika Iwanowska, Ludwig Feigl

The dependence of the formation of ferroelastic stripe domain patterns on the thermal history is investigated by detailed piezoresponse force microscopy and X-ray diffraction experiments after and during annealing of tensile strained tetragonal Pb(Ti,Zr)O- ...

Persistent conductive footprints of 109 degrees domain walls in bismuth ferrite films

Nava Setter, Enrico Colla, Igor Stolichnov, Monika Iwanowska

Using conductive and piezoforce microscopy, we reveal a complex picture of electronic transport at weakly conductive 109 degrees domain walls in bismuth ferrite films. Even once initial ferroelectric stripe domains are changed/erased, persistent conductive ...

Domain wall conduction in bismuth ferrite thin films

Monika Iwanowska

Ferroelectrics are materials with a spontaneous electrical polarization, which can be switched by an applied electric field between two or more stable orientations permitted by symmetry. The regions where the ferroelectric material is polarized in one dire ...

Polarization Reversal in BiFeO3 Capacitors: Complex Behavior Revealed by PFM

Paul Muralt, Nava Setter, Alexander Tagantsev, Enrico Colla, Igor Stolichnov, Monika Iwanowska

Polarization reversal in BiFeO3 (BFO) thin films in a parallel-plate capacitor configuration has been explored using piezo-force microscopy (PFM). Through-electrode mapping of the local piezoresponse allows for direct observation of the domain growth, whic ...
