Description
This fellowship opportunity at the Naval Research Laboratory (NRL) supports theoretical research focused on discovering and designing semiconductor nanostructures whose lowest energy exciton states are bright rather than dark. Building on prior work published in Nature (2018) that identified bright triplet excitons in cesium lead halide perovskite nanocrystals, this research aims to understand and "break" the dark exciton influence that limits fluorescence in most semiconductors.
The goal is to explore fundamental physics and develop strategies to engineer new classes of semiconductor nanostructures with bright excitons. Such materials have the potential to revolutionize optoelectronic devices, including biological emitters, super-radiant materials, and laser-gain media with unprecedented performance.
Key Research Themes
- Theoretical modeling of exciton states in low-dimensional semiconductor nanostructures
- Investigation of mechanisms enabling bright ground exciton states
- Design principles for nanostructures that overcome dark exciton limitations
- Potential applications in fast emitters, lasers, and biological imaging
