Impedance Spectroscopy Study in the vicinity of Ferroelectric Phase Transition
Hitesh Borkar, M Tomar, Vinay Gupta +1
An impedance spectroscopy (IS) is a versatile tool to study the effect of grains (bulk), grain boundaries and electrode-electrolyte interface on dielectric and electrical propertie…
Faceting Oscillations in Nano-Ferroelectrics
J. F. Scott, Ashok Kumar
We observe periodic faceting of 8-nm diameter ferroelectric disks on a 10 s time-scale when thin Pb(Zr0.52Ti0.48)O3 (PZT) film is exposed to constant high-resolution transmission e…
Photoconductivity and photo-detection response of multiferroic bismuth iron oxide
Avneesh Anshul, Hitesh Borkar, Paritosh Singh +3
We report visible light detection with in-plane BiFeO3 (BFO) thin films grown on pre-patterned inter-digital electrodes. In-plane configured BFO film displayed photocurrents with a…
Multifunctional Magnetoelectric Materials for Device Applications
N. Ortega, Ashok Kumar, J. F. Scott +1
Mutiferroics are a novel class of next generation multifunctional materials, which display simultaneous magnetic spin, electric dipole, and ferroelastic ordering, and have drawn in…
Ferroelectric and Photovoltaic Properties of Transition Metal doped Pb(Zr0.14Ti0.56Ni0.30)O3-delta Thin Films
Shalini Kumari, Nora Ortega, Ashok Kumar +2
We report nearly single phase Pb(Zr0.14Ti0.56Ni0.30)O3-delta(PZTNi30) ferroelectric having large remanent polarization (15-30 μC/cm2), 0.3-0.4 V open circuit voltage (VOC), reduced…
