Establishing quasi-linear quadrupole functional topology by oxygen-vacancy engineering at a ferroelectric domain wall
Hemaprabha Elangovan, Maya Barzilay, Jiawei Huang +3
Oxygen vacancies in two-dimensional metal-oxide structures garner much attention due to unique conductive, magnetic and even superconductive functionalities they induce. Ferroelect…
Formation and manipulation of domain walls with 2-nm domain periodicity in without contact electrodes
Maya Barzilay, Yachin Ivry
Interfaces at the two-dimensional limit in oxide materials exhibit a rich span of functionality that differs significantly from the bulk behavior. Among such interfaces, domain wal…
Surface nucleation of the paraelectric phase in ferroelectric BaTiO3: Atomic scale mapping
Maya Barzilay, Hemaprabha Elangovan, Yachin Ivry
In ferroelectricity, atomic-scale dipole moments interact collectively to produce strong electro-mechanical coupling and switchable macroscopic polarization. Hence, the functionali…
Epitaxial TiOx Surface in Ferroelectric BaTiO3: Native Structure and Dynamic Patterning at the Atomic Scale
Maya Barzilay, Tian Qiu, Andrew M. Rappe +1
Surfaces and interfaces of ferroelectric oxides exhibit enhanced functionality, and therefore serve as a platform for novel nano and quantum technologies. Experimental and theoreti…
