High-Temperature Photocurrent Mechanism of \b{eta}-Ga2O3 Based MSM Solar-Blind Photodetectors
B. R. Tak, Manjari Garg, Sheetal Dewan +5
High-temperature operation of metal-semiconductor-metal (MSM) UV photodetectors fabricated on pulsed laser deposited \b{eta}-Ga2O3 thin films has been investigated. These photodete…
Optically Controlled Polarization in Highly Oriented Ferroelectric Thin Films
Hitesh Borkar, M Tomar, Vinay Gupta +3
The out-of-plane and in-plane polarization of (Pb0.6Li0.2Bi0.2)(Zr0.2Ti0.8)O3(PLBZT) thin film has studied in the dark and under illumination of a weak light source of a comparable…
Giant Enhancement in Ferroelectric Polarization under Illumination
Hitesh Borkar, Vaibhav Rao, M Tomar +3
We report optical enhancement in polarization and dielectric constant near room temperature in Pb0.6Li0.2Bi0.2Zr0.2Ti0.8O3 (PLBZT) electro-ceramics; these are doubly substituted me…
Novel optically active lead-free relaxor ferroelectric (Ba0.6Bi0.2Li0.2)TiO3
Hitesh Borkar, Vaibhav Rao, Soma Dutta +6
We discovered a near room temperature lead-free relaxor-ferroelectric (Ba0.6Bi0.2Li0.2)TiO3 (BBLT) having A-site compositional disordered ABO3 perovskite structure. Microstructure-…
Anomalous change in leakage and displacement currents after electrical poling on lead-free ferroelectric ceramics
Hitesh Borkar, M. Tomar, Vinay Gupta +2
We report the polarization, displacement current and leakage current behavior of a trivalent nonpolar cation Al cation substituted lead free ferroelectric NBT-BT electroceramics wi…
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…
