Journal ArticleDOI
Nanoscale mapping of ion diffusion in a lithium-ion battery cathode
Nina Balke,Stephen Jesse,Anna N. Morozovska,Eugene A. Eliseev,Ding-Wen Chung,Yoongu Kim,Leslie A. Adamczyk,R. E. García,Nancy J. Dudney,Sergei V. Kalinin +9 more
TL;DR: The spatial variation of lithium-ion diffusion times in the battery-cathode material LiCoO(2) is probed at a resolution of ∼100 nm by using an atomic force microscope to both redistribute lithium ions and measure the resulting cathode deformation, revealing that the diffusion coefficient increases for certain grain orientations and single-grain boundaries.
Journal ArticleDOI
Observation of a periodic array of flux-closure quadrants in strained ferroelectric PbTiO3 films
Yun-Long Tang,Yinlian Zhu,Xiuliang Ma,Albina Y. Borisevich,Anna N. Morozovska,Eugene A. Eliseev,Wanxiao Wang,Yujia Wang,Yaobin Xu,Zhenqian Zhang,Stephen J. Pennycook,Stephen J. Pennycook +11 more
TL;DR: Not only the atomic morphology of the flux-closure quadrant but also a periodic array of flux closures in ferroelectric PbTiO3 films, mediated by tensile strain on a GdScO3 substrate are observed.
Journal ArticleDOI
Local polarization dynamics in ferroelectric materials
TL;DR: In this article, the authors summarize the recent progress in applications of piezoresponse force microscopy (PFM) for imaging, manipulation and spectroscopy of ferroelectric switching processes.
Journal ArticleDOI
Enhanced electric conductivity at ferroelectric vortex cores in BiFeO 3
Nina Balke,B. Winchester,Wei Ren,Ying-Hao Chu,Anna N. Morozovska,Eugene A. Eliseev,Mark Huijben,Rama K. Vasudevan,Petro Maksymovych,Jason Britson,Stephen Jesse,Igor Kornev,Ramamoorthy Ramesh,Laurent Bellaiche,Long Qing Chen,Sergei V. Kalinin +15 more
TL;DR: In this paper, the authors explore electronic transport at artificially created ferroelectric vortices in BiFeO3 thin films and demonstrate the creation of one-dimensional conductive channels activated at voltages as low as 1 V.
Journal ArticleDOI
CuInP2S6 room temperature layered ferroelectric
Alex Belianinov,Qian He,A. Dziaugys,Petro Maksymovych,Eugene A. Eliseev,Albina Y. Borisevich,Anna N. Morozovska,Juras Banys,Yulian M. Vysochanskii,Sergei V. Kalinin +9 more
TL;DR: The existence of stable polarization in a van-der-Waals crystal naturally points toward new strategies for ultimate scaling of polar materials, quasi-2D, and single-layer materials with advanced and nonlinear dielectric properties that are presently not found in any members of the growing "graphene family".
