Direct studies of domain switching dynamics in thin film ferroelectric capacitors
Alexei Gruverman,Brian J. Rodriguez,C. Dehoff,C. Dehoff,J. D. Waldrep,Angus I. Kingon,Robert J. Nemanich,Jeffrey S. Cross +7 more
TL;DR: An experimental approach for direct studies of the polarization reversal mechanism in thin film ferroelectric capacitors based on piezoresponse force microscopy (PFM) in conjunction with pulse switching capabilities is presented in this paper.
Journal ArticleDOI
Mechanical stress effect on imprint behavior of integrated ferroelectric capacitors
Alexei Gruverman,Brian J. Rodriguez,Angus I. Kingon,Robert J. Nemanich,Alexander K. Tagantsev,Jeffrey S. Cross,M. Tsukada +6 more
TL;DR: In this article, stress-induced changes in the imprint and switching behavior of (111)-oriented Pb(Zr,Ti)O3 (PZT)-based capacitors have been studied using piezoresponse force microscopy.
Journal ArticleDOI
Domain growth kinetics in lithium niobate single crystals studied by piezoresponse force microscopy
Brian J. Rodriguez,Robert J. Nemanich,Angus I. Kingon,Alexei Gruverman,Sergei V. Kalinin,Kazuya Terabe,Xiaolian Liu,Kenji Kitamura +7 more
TL;DR: In this article, the authors investigated the kinetics of sidewise domain growth in an inhomogeneous electric field by measuring the lateral domain size as a function of the voltage pulse magnitude and duration using piezoresponse force microscopy.
Journal ArticleDOI
Nanoscale Electromechanics of Ferroelectric and Biological Systems: A New Dimension in Scanning Probe Microscopy
Sergei V. Kalinin,Brian J. Rodriguez,Stephen Jesse,Edgar Karapetian,Boris Mirman,Eugene A. Eliseev,Anna N. Morozovska +6 more
TL;DR: In this paper, the authors give an overview of the fundamental image formation mechanism in piezoresponse force microscopy (PFM) and summarize recent theoretical and technological advances.
Journal ArticleDOI
Vortex Polarization States in Nanoscale Ferroelectric Arrays
Brian J. Rodriguez,Xingsen Gao,Lifeng Liu,Woo Lee,Ivan Naumov,Alexander M. Bratkovsky,Dietrich Hesse,Marin Alexe +7 more
TL;DR: The observed presence of an in-plane polarization component in nominally (001) oriented PZT suggests the existence of a significant deviation from the regular tetragonal structure that allows the formation of complex core-polarization states.
