Defect-Rich Size-Selected Nanoclusters and Nanocrystalline Films of Titanium (IV) Oxide and Tantalum (IV) Oxide for Efficient Photocatalyst and Electroforming-Free Memristor Applications
(University of Waterloo, 2016-05-16)Transition metal oxides, TiO2 and Ta2O5, are two of the most extensively studied wide bandgap semiconductor materials (with high work functions). Due to their suitable band edge positions for hydrogen evolution and exceptional ... -
Defect-rich Titanium (IV) Oxide and Zirconium (IV) Oxide Nanostructures for Ultra-efficient Photocatalyst and High-Tc Dilute Ferromagnetic Semiconductor Applications
(University of Waterloo, 2016-05-16)In transparent conductive oxide nanostructures, oxygen vacancy defects (neutral, singly charged, and doubly charged defects) are found to be one of the most important and prevalent defects due to the enhancement of light ... -
One-dimensional Nanostructures of Hafnium Oxides: Fabrication with and without Ti/Fe Doping, and Magnetic Properties
(University of Waterloo, 2022-01-10)Since the discovery of giant magnetoresistance (GMR) in the late 1980s, which marked the emergence of spintronic technology, the integration of conventional semiconductor-based electronics with spintronics has always been ... -
Photophysical and Optoelectronic Properties of Pristine, Doped and Surface-Functionalized Two-Dimensional Zinc Oxide Nanostructures
(University of Waterloo, 2016-01-20)As one of the most studied transparent conducting oxides, zinc oxide (ZnO) has received a lot of attention due to its physical, chemical, optical and optoelectronic properties. The present study focusses on the photophysical ... -
Site-specific Chemistry of Sulfur-containing Amino Acids on Si(111)-√3×√3-Ag: Bioorganic Nanostructured Film Growth and Adsorbate-induced Metal Cluster Formation Governed by Surface Defects
(University of Waterloo, 2019-09-24)The interfacial interactions and film growth mechanisms of sulfur-containing amino acids on Si(111)-√3×√3-Ag are investigated by using x-ray photoelectron spectroscopy (XPS) and scanning tunneling microscopy (STM) at room ...
