Observation, Evidence and Origin of Room Temperature Magnetodielectric Effect in Mn doped LaGaO3
Hari Mohan Rai, Shailendra K. Saxena, Vikash Mishra +2
We report an observation of room temperature magnetodielectric (RTMD) effect in Mn doped LaGaO3. Results of frequency dependent magnetoresistance (FDMR) measurements discards the p…
Metastable behavior of Urbach tail states in BaTiO3 across phase transition
Vikash Mishra, Archna Sagdeo, Kamal Warshi +4
The temperature dependent diffuse reflectance spectroscopy measurements were carried out on the polycrystalline samples of BaTiO3 across the tetragonal to cubic structural phase tr…
Comment on Half metallicity along the edge of zigzag boron nitride nanoribbons (Phys. Rev. B 78, 205415 (2008)
Hari Mohan Rai, Rajesh Kumar, Pankaj R. Sagdeo +2
We would like to comment that the prediction of Half-mtallicity in only B edge H-passivated zigzag boron nitride nanoribbons (ZBNNR-BH), by Zheng et al.1, is not correct as their i…
Optical bandgap and bowing parameter for Fe doped LaGaO3
P. R. Sagdeo, Preetam Singh, Hari Mohan Rai +3
The polycrystalline samples of LaGa1-xFexO3 have been prepared by standard solid state reaction route. The phase purity of the prepared samples is confirmed by powder xray diffract…
Role of Metal Nanoparticles on porosification of silicon by metal induced etching (MIE)
Shailendra K. Saxena, Priyanka Yogi, Pooja Yadav +6
Porosification of silicon (Si) by metal induced etching (MIE) process have been studies here to understand the etching mechanism. The etching mechanism has been discussed on the ba…
Half-metallicity in Armchair Boron Nitride Nanoribbons: A First-Principles Study
Hari Mohan Rai, Shailendra K. Saxena, Vikash Mishra +5
Using density functional theory, we predict half-metallicity in edge hydrogenated armchair boron nitride nanoribbons (ABNNRs). The predicted spin polarization is analyzed in detail…
Interplay between Phonon Confinement and Fano Effect on Raman line shape for semiconductor nanostructures: Analytical study
Priyanka Yogi, Shailendra K. Saxena, Suryakant Mishra +7
Theoretical Raman line shape functions have been studied to take care of quantum confinement effect and Fano effect individually and jointly. The characteristics of various Raman l…
Room temperature magnetodielectric studies on Mn doped LaGaO3
Hari Mohan Rai, Ravikiran Late, Shailendra Saxena +4
The polycrystalline samples of LaGa1-xMnxO3 (0<x<0.3) has been prepared by solid state reaction route. The phase purity of these samples has been confirmed by powder x-ray diffract…
Intrinsic Half-metallicity in Edge Fluorinated Armchair Boron Nitride Nanoribbons
Hari Mohan Rai, Shailendra K Saxena, Vikash Mishra +5
We predict intrinsic half-metallicity in armchair boron nitride nanoribbons (ABNNRs) via edge fluorination. The stability, electronic and magnetic properties of bare and edge fluor…
Comparison of porous silicon prepared using metal-induced etching (MIE) and laser-induced etching (LIE)
Shailendra K. Saxena, Vivek Kumar, Hari M. Rai +6
Porous silicon (p-Si), prepared by two routes (metal induced etching (MIE) and laser induced etching (LIE)) have been studied by comparing the observed surface morphologies using S…
Evolution of Asymmetric Raman line-shape from nano-structures
Rajesh Kumar, Gayatri Sahu, Shailendra K. Saxena +2
A step-by-step evolution of an asymmetric Raman line-shape function from a Lorentzian line-shape is presented here for low dimensional semiconductors. The evolution reported here i…
