Structural, dielectric, and ferroelectric characteristics of the low-temperature sintered 65PMN-35PT sample for electroceramic applications
B. Ramachandran, N. Sudarshan, G. Mangamma +1
A single-phase 65PMN-35PT ceramic was synthesized at a relatively low temperature (875 oC) using a modified columbite method. X-ray diffraction analysis confirmed the single-phase…
An analysis of derivative absorption spectroscopy of multiferroic bismuth ferrite materials
Ramachandran Balakrishnan
The probability density function (PDF) and cumulative density function (CDF) of bulk BiFeO3, nanostructured BiFeO, and thick film of BiFeO were studied in detail based…
Investigation of electronic energy levels in a weak ferromagnetic oxygen-deficient BiFeO2.85 thick film using absorption and X ray photoelectron spectroscopic studies
Ramachandran Balakrishnan, Ambesh Dixit, Mamidanna Sri Ramachandra Rao
We grew a 2 micron thick film of single-phase BiFeO3 on a Si (100) substrate by pulsed laser deposition with a substrate temperature of 575 oC and an oxygen partial pressure of 0.0…
Probing electronic transitions and defect-induced Urbach tail bands in functional perovskite oxides using diffuse reflectance
Ramachandran Balakrishnan, Priyambada Sahoo, Balamurugan Karuppannan +1
We conducted a detailed study of electronic transitions and defects induced Urbach tail bands in various functional perovskite oxides (V2O5, BaSnO3, PbZr0.52Ti0.48O3, BiMnO3, and B…
