Induced Giant Piezoelectricity in Centrosymmetric Oxides
D. -S. Park, M. Hadad, L. M. Rimer +11
Piezoelectrics are materials that linearly deform in response to an applied electric field. As a fundamental prerequisite, piezoelectric material must possess a non centrosymmetric…
Latent mechanisms of polarization switching from in situ electron microscopy observations
Reinis Ignatans, Maxim Ziatdinov, Rama Vasudevan +3
In situ scanning transmission electron microscopy enables observation of the domain dynamics in ferroelectric materials as a function of externally applied bias and temperature. Th…
Decoding the mechanisms of phase transitions from in situ microscopy observations
Mani Valleti, Reinis Ignatans, Sergei V. Kalinin +1
Temperature-induced phase transition in BaTiO3 has been explored using the machine learning analysis of domain morphologies visualized via variable-temperature scanning transmissio…
Individual Barkhausen pulses of ferroelastic nanodomains
Reinis Ignatans, Dragan Damjanovic, Vasiliki Tileli
Ferroelectric materials, upon electric field biasing, display polarization discontinuities known as Barkhausen jumps, a subclass of a more general phenomenon known as crackling noi…
Local hard and soft pinning of 180 domain walls in BaTiO probed by in situ transmission electron microscopy
Reinis Ignatans, Dragan Damjanovic, Vasiliki Tileli
We report on the electric field response of 180 degree nanodomain walls in BaTiO using in situ electrical biasing in transmission electron microscopy (TEM). The sample is biase…
Electrochemical Surface Modification of a 2D MoS2 Semiconductor
Martina Lihter, Michael Graf, Damir Iveković +4
The surface modification of 2D semiconducting materials, such as transition metal dichalcogenides (TMDCs), is becoming important for a diverse range of applications, such as biosen…
