Magnetic excitations and exchange parameters of a nickel chain compound PbMnNiTeO: Neutron scattering and density functional theory studies
S. Uthayakumar, D. T. Adroja, Amit Pokhriyal +10
We have investigated the quasi-one dimensional Ni-chain compound PbMnNiTeO using theoretical DFT calculations, inelastic neutron scattering and optical spectrosc…
Strain induced stabilization of high symmetry phase in MAPbBr3 perovskite
Shankar Dutt, Joydipto Bhattacharya, Kailash Kumar +3
Structural phase transitions in the organic inorganic metal halide perovskites are driven via rearrangement of methylammonium cation and distortion in the PbX6 octahedra. Compositi…
Strain Induced Relaxor-type Ferroelectricity Near Room Temperature in Delafossite CuCrO2
Preeti Pokhriyal, Ashok Bhakar, Parasmani Rajput +5
Polycrystalline samples of CuCrO2 were synthesized by solid state reaction method. Temperature dependent dielectric measurements, synchrotron x-ray diffraction (SXRD), pyroelectric…
Generalization of Phonon Confinement Model for Interpretation of Raman Line-Shape from Nano-Silicon
Manushree Tanwar, Priyanka Yogi, Simran Lambora +5
A comparative analysis of two Raman line-shape functions has been carried out to validate the true representation of experimentally observed Raman scattering data for semiconductin…
Tent--Shaped Surface Morphologies of Silicon: Texturization by Metal Induced Etching
Priyanka Yogi, Deepika Poonia, Suryakant Mishra +4
Nano--metal/semiconductor junction dependent porosification of silicon (Si) has been studied here. The silicon (Si) nanostructures (NS) have been textured on n-- and p-- type silic…
Three-fold Constructive Perturbation for Significant Enhancement in Field Emission from Nickel Oxide Nano-Thorn
Suryakant Mishra, Priyanka Yogi, Shailendra K. Saxena +3
A power efficient and stable field emission (FE) has been reported here from Nickel Oxide nanostructures. Modification in device geometry and surface micro- (nano-) structure has b…
