Transition metal doping of semiconductor nanomaterials, particularly magnetic dopant ions, is of great interest for the synthesis of diluted magnetic semiconductors (DMS) with spintronic-based applications. The incorporation of magnetic ions into quantum dots (QDs) would be particularly useful since the quantum confinement of these materials is theorized to enhance magneto-optical related properties. One major challenge in this field is the segregation of dopant ions towards the outer regions of the QD due to the exclusion of dopants during the nucleation process, thereby inhibiting the magneto-optical properties. In this dissertation, we address the dopant segregation challenge by exploring the underlying mechanisms …

Metal halide perovskite solar cells (PSCs) have revolutionized the field of thin film photovoltaics. Within a decade, the power conversion efficiencies (PCEs) have increased at a phenomenal rate, rising from 3.8% to more than 25% in single-junction devices, moving them ahead of the current silicon-based technology. The high efficiencies of perovskite solar cells (PSCs) and their other unique properties arise from a combination of organic and inorganic components and electronic-ionic conduction, making them excellent candidates for a plethora of applications. However, PSCs face a significant—and ironic—roadblock to commercialization: these light-harvesting materials degrade under sunlight—the very condition they would need …
