The National Science Foundation (NSF) awarded a $125,183 EAGER (Early-concept Grants for Exploratory Research) project grant to the Regents of the University of Michigan under the Engineering program (CFDA 47.041) to research and develop a novel heterobarrier layer for light-emitting diodes (LEDs) that can improve their thermal, power, and performance efficiency. The goal is to demonstrate the proof-of-concept for in-situ spectral phonon recycling in LEDs, which could lead to significant national energy savings and enhanced thermal management for LED devices. The one-year project combines simulation modeling of phonon transport and recycling behavior with fabrication and testing of the optimal heterobarrier LED design. If successful, this research could advance the Department of Energy's solid-state lighting R&D goals for 2035.
