Room temperature concurrent formation of ultra-dense arrays of ferroelectric domain walls

Nava Setter, Alexander Tagantsev, Petr Yudin, Ludwig Feigl, Mahamudu Mtebwa, Konstantin Shapovalov

Properties of ferroelectric domain walls are attractive for future nano- and optoelectronics. An important element is the potential to electrically erase/rewrite domain walls inside working devices. Dense domain wall patterns, formed upon cooling through t ...

Bent Ferroelectric Domain Walls as Reconfigurable Metallic-Like Channels

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Tomas Sluka, Enrico Colla, Petr Yudin, Ludwig Feigl, Konstantin Shapovalov, Xiankui Wei, Arnaud Robert André Crassous

Use of ferroelectric domain-walls in future electronics requires that they are stable, rewritable conducting channels. Here we demonstrate nontherrnally activated metallic-like conduction in nominally uncharged, bent, rewritable ferroelectric-ferroelastic ...

Compliant ferroelastic domains in epitaxial Pb(Zr, Ti)O-3 thin films

Nava Setter, Silviu Cosmin Sandu, Ludwig Feigl

Ordered patterns of highly compliant ferroelastic domains have been created by use of tensile strained epitaxial Pb(Zr, Ti)O-3 thin films, of very low defect density, grown on DyScO3 substrates. The effect of 180 degrees switching on well-ordered a/c 90 de ...

Superdomain Structure in Epitaxial Tetragonal PZT Thin Films Under Tensile Strain

Nava Setter, Ludwig Feigl

The a/c domain pattern of tetragonal PbZr0.10Ti0.90O3 thin films under tensile misfit strain is investigated by piezoresponse force microscopy and X-ray diffraction. The results show a hierarchical ordering of the dense a/c domain structure into larger sup ...

Controlled stripes of ultrafine ferroelectric domains

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Tomas Sluka, Petr Yudin, Silviu Cosmin Sandu, Ludwig Feigl, Mahamudu Mtebwa, Konstantin Shapovalov, Xiankui Wei

In the pursuit of ferroic-based (nano) electronics, it is essential to minutely control domain patterns and domain switching. The ability to control domain width, orientation and position is a prerequisite for circuitry based on fine domains. Here, we deve ...
