Functional Ion Defects in Transition Metal Oxides
TL;DR: Dynamically tuning the concentration and profile of ions and vacancies in transition metal oxides provides a route to control of new functionalities that have led to the widespread use of oxides and may form the basis of new device paradigms, such as the control of magnetism with electric fields.
Journal ArticleDOI
Differentiating Ferroelectric and Nonferroelectric Electromechanical Effects with Scanning Probe Microscopy.
Nina Balke,Petro Maksymovych,Stephen Jesse,Andreas Herklotz,Alexander Tselev,Chang-Beom Eom,Ivan I. Kravchenko,Pu Yu,Pu Yu,Sergei V. Kalinin +9 more
TL;DR: This work systematically analyzes PFM responses on ferroelectric and nonferroelectric materials and demonstrates that mechanisms unrelated to ferroElectricity can induce ferro electric-like characteristics through charge injection and electrostatic forces on the tip.
Journal ArticleDOI
Dynamic Conductivity of Ferroelectric Domain Walls in BiFeO3
Peter Maksymovych,Jan Seidel,Jan Seidel,Ying-Hao Chu,Pingping Wu,Arthur P. Baddorf,Long Qing Chen,Sergei V. Kalinin,Ramamoorthy Ramesh,Ramamoorthy Ramesh +9 more
TL;DR: The measurements identified that subtle and microscopically reversible distortion of the polarization structure at the domain wall is at the origin of the dynamic conductivity, likely to be a universal property of topological defects in ferroelectric semiconductors.
Journal ArticleDOI
Direct observation of ferroelectric field effect and vacancy-controlled screening at the BiFeO3/LaxSr1-xMnO3 interface.
Young-Min Kim,Anna N. Morozovska,Eugene A. Eliseev,Mark P. Oxley,Rohan Mishra,Sverre Magnus Selbach,Tor Grande,Sokrates T. Pantelides,Sergei V. Kalinin,Albina Y. Borisevich +9 more
TL;DR: An unexpected ~5% lattice expansion for regions with negative polarization charge is demonstrated, with a concurrent anomalous decrease of the Mn valence and change in oxygen K-edge intensity, which underline the non-trivial role of electrochemical phenomena in determining the functional properties of oxide interfaces.
Journal ArticleDOI
Atomic Polarization and Local Reactivity on Ferroelectric Surfaces: A New Route toward Complex Nanostructures
Sergei V. Kalinin,Dawn A. Bonnell,Tony Alvarez,X. Lei,Zonghai Hu,J. H. Ferris,Qi Zhang,Steve Dunn +7 more
TL;DR: In this paper, photo reduction is used to produce metal nanoparticles in predefined locations on an oxide substrate, and organic molecules are reacted selectively to the particles, which can be repeated to develop complex structures consisting of nanosized elements of semiconductors, metals, or functional organic molecules.
