Nanoscale materials possess unique optoelectronic properties that have the potential to significantly improve the performance of many types of devices. The research goal of this program is to speed discovery of novel materials for devices by using computational modeling to guide experimental production of nanomaterials. To assess the potential of the vast array of candidate materials in device applications, efficient methods of theoretical modeling and experimental synthesis must be developed. Theoretical efforts during the first year of this project have focused on two areas: calculation of the properties of semiconductor quantum dots with explicit consideration of size, shape and substrate using an efficient effective potential method; and simulation of electromagnetic phenomena near pristine and atomically doped carbon nanotubes. Experimental work during the first year involved the use of ultrafast pulsed laser deposition to produce semiconductor quantum dots, and the development of a new experimental apparatus to produce semiconductor nanowires. This project is also intended to support STEM education at North Carolina Central University (NCCU) by increasing access to research opportunities for undergraduate and graduate students and by providing materials for demonstrations and laboratory activities for undergraduate courses.
