Research Topic:

Synthesis and characterization of nano semiconductors

About the work:
In the materials science field, the nano semiconducting materials are most important to change the world in different aspects. Nanomaterials are extensively explored in the field of materials science and they exhibit significantly unique and interesting magnetic, mechanical, electronic, thermal, catalytic and optical properties in comparison with bulk materials. In the last couple of decades, synthesis of nanosized semiconducting materials is most interesting to materials researchers because of their potential applications. The electron density analysis of the materials provides an explanation for the physical and chemical properties. The detailed analysis of the electron density distribution of nano semiconducting materials is still lacking across the present research communities. The present thesis deals and concentrates towards the electron density distribution of nano semiconducting materials determined using experimental X-ray diffraction data. In this research topic deals about the electron density distribution analysis of nano semiconducting materials such as ZnS, TiO2, NiO, Ga doped ZnO, Mn doped SnO2, Mn doped CeO2 and Mn doped ZrO2 nanostructures.
