The thesis covers almost all the relevant work regarding the device fabrication based on NiO and ZnO semiconductors. The synthesis, morphology and physical properties of grown semiconducting materials are discussed in detail. The role of anion has been discussed to understand different morphologies of ZnO nanostructures. Use NiO nanostructures as chemical sensor in order to detect the zinc ion. Synthesis of composite p-type NiO/n-type ZnO nanostructures by low temperature aqueous chemical growth method, their optical properties, transport mechanism and band alignment of proposed heterojunction have also been covered in this dissertation. NiO/ZnO composite nanostructures have also been utilized to fabricate UV photo detector and LEDs.
Special features
• A detailed coverage of background/motivation.
• Focusing on nanotechnology with respect to nanomaterials along with their properties.
• A section covers information regarding the grown oxide materials.
• Results and discussion section is describing the synthesis, properties and few applications of NiO, ZnO and their composite nanostructures.
