Ionically-mediated electromechanical hysteresis in transition metal oxides
Yunseok Kim, Anna N. Morozovska, Amit Kumar +5
Electromechanical activity, remanent polarization states, and hysteresis loops in paraelectric TiO2 and SrTiO3 are observed. The coupling between the ionic dynamics and incipient f…

Cross talk by extensive domain wall motion in arrays of ferroelectric nanocapacitors
Yunseok Kim, Hee Han, Ionela Vrejoiu +3
We report on extensive domain wall motion in ferroelectric nanocapacitor arrays investigated by piezoresponse force microscopy. Under a much longer or higher bias voltage pulse, co…
