Highly-textured phase pure Cu2O thin films have been grown on fluorine-doped SnO2 substrates by a simple electrodeposition technique with varying deposition voltages (-0.3 to -1.0 V). Surface morphology characterization by scanning electron microscopy revealed that the deposited thin films coherently carpet the underlying substrate and are composed...

The structural, elastic, mechanical, electronic and optical properties of lead free noncentrosymmetric ZnMO3 (M = Ge, Sn) have been studied using density functional theory based simulation methods. The optimized lattice parameters were compared with reported experimental and theoretical values and were found good agreement. The compounds are mechan...

Large size high quality Li7La3Zr2O12 single crystals were grown successfully by floating zone (FZ) technique. The grown crystals were characterized by X-ray di�raction, etch pits density measurement, Impedance analysis, Vibrating sample magnetometry (VSM) and UV-Visible spectrometry. The investigation of structural, electrical, optical properties a...

The comprehensive study was found out to evaluate the concentration of different water qualities of the Karnaphuli river. Samples were collected from ten points (Bhandor Ghat to Bhakoliya Khal Ghat) in three seasons (winter, rainy, and spring) during the Hydrological Year 2014-2015 for continuous monitoring. Collected samples were analyzed for find...

Phase pure Cu2O is one of the most desirable p-type absorber materials for ZnO based all-oxide solar cell because of its reported direct bandgap(~2.17 eV) and a suitable band alignment with n-type ZnO electrodes. Highly textured phase pure Cu2O thin films have been grown by a simple electrodeposition technique with varying cathodic potentials (-0.3...

Origination of defects and loss of Na during the sintering process are the major problems for the conventional solid-state synthesis technique to form sodium (Na) doped lanthanum manganite. To minimize defect and Na loss during the sintering process, the sodium (Na) doped lanthanum manga-nite with 15% substitution of La by Na (La 0.85 Na0.15MnO3...
