- Experimental evidence of the photonic bandgap and defect effect in Si-SiO2 multilayer structures

This work aims to master both experimental and theoretical techniques to get the set of conditions to deposit alternating silicon and silica layers to obtain one-dimensional photonic crystal. It shows how trapping light can be obtained by appropriately introducing defects in the structure.

Homogeneity regions of ZnTe, CdTe, CdSe, and CdS were determined. The general scheme of homogeneity range for all studied compounds has been constructed according to which “wurtzite-zincblende” transition occurred by peritectic reactions from both Metal and Chalcogen rich sides. The analysis of nonstoichiometry as a solid solution of over-stoichiometric component in the above compounds has been fulfilled. The thermodynamic parameters of stability of “wurtzite-zincblende” transition were estimated.
- Studies on growth and nucleation kinetics of Piperazinium L-Tartrate (PPLT) single crystal

PPLT single crystal was grown by slow cooling technique. The powder XRD analysis shows the crystalline nature of the compound. The induction period was evaluated using the solubility. The interfacial tension are calculated experimentally and compared with the theoretical values. The nucleation parameters such as Gibbs free energy change (ΔG*), radius of critical nuclei (r*), nucleation rate (J) and the number of molecules present in the nucleus (i*) are determined experimentally. The NLO efficiency of the PPLT single crystal is found to be 0.9 times greater than that of KDP.

Large-area and uniform thickness nano-sheet structured CuS thin films on ITO glass have been prepared by the one-step electrodeposition method from a dimethyl sulfoxide solution. Thin films of completely preserved nano-sheet like morphology of CuyS (y = 1.75, 1.8, 1.95, and 2.0) are grown by vacuum annealing as-deposited CuS. The 500°C sample heated for 10 hours was nearly converted to single phase of Cu2S with y ∼ 2.
- Leaf-like copper oxide nanocrystals synthesized by a gas-liquid diffusion method at room temperature

Leaf-like copper oxide nanocrystals have been synthesized by a gas-liquid diffusion method in pure aqueous solution at room temperature. Experiment results showed that only when the concentration of copper ion was low enough (0.005 M) that the leaf-like copper oxide copper oxide could be obtained directly. Additionally, the forming mechanism of copper oxide was also proposed based on the observed results.
