Summary of Work

Colloidal nanocrystals are a very interesting material system with inherent flexibility that exists well beyond their size tunable band gap. The choice in boundary conditions on their electronic states is quite large given the wide variety of semiconductor materials, heterostructure configurations, and geometric dimensions available. Thus, these nanocrystals serve as a rich playground for observing single, paired, and multicharge dynamics under a range of parameter configurations. Although ferromagnetic doping effects on these electronic states have certainly been a popular avenue of exploration, paramagnetic effects have remained largely overlooked.
