The National Science Foundation (NSF) awarded a Project Grant in the amount of $400,000 to Brown University to develop new experimental techniques for studying charge transport dynamics in semiconductor and thin film materials. Specifically, the research aims to establish "non-local THz nanoscopy" methods that leverage terahertz (THz) spectroscopy to provide high spatial and temporal resolution characterization of charge carrier dynamics in materials such as gallium nitride and perovskite solar cells. The project, funded through NSF's Engineering Directorate (CFDA 47.041), will extend THz techniques to the nanoscale to gain new insights into lateral charge transport across interfaces and defects in these material systems, which are critical for emerging device applications. The award period is from August 15, 2023 through July 31, 2026.
