1	SURFACE CHEMISTRY CONTROL OF 2D NANOMATERIAL MORPHOLOGIES, OPTOELECRONIC RESPONSES, AND PHYSICOCHEMICAL PROPERTIES Jacob Thomas Lee (12431955) 12 July 2022 (has links) <p>This dissertation describes how the surface chemistries of 2D nanomaterials can be modified to alter overall material properties. Specifically, through a focus of the ligand-surface atom bonding in addition to the overall ligand structure we highlight the ability to direct morphological outcomes in lead free halide perovskites, maximize optoelectronic responses in substoichiometric tungsten oxide, and alter physicochemical properties titanium carbide MXenes. </p> Transition metal chemistry Macromolecular materials Nanochemistry Optical properties of materials Physical properties of materials Structure and dynamics of materials Supramolecular chemistry Colloid and surface chemistry Localized Surface Plasmon Resonance MXenes WO3-x 2D nanomaterials perovskite lead-free perovskite surface chemistry covalent attachment 2D morphology optoelectronic characteristics Inorganic Chemistry Optical Properties of Materials Physical Chemistry of Materials Synthesis of Materials Transition Metal Chemistry Chemical Characterisation of Materials Colloid and Surface Chemistry
