The National Science Foundation (NSF) awarded a $411,378 Project Grant from the Engineering (ENG) program to The University of Iowa. This 3-year grant, awarded on August 15, 2023, will fund research to develop phonon polariton-based infrared photodetectors and optoelectronics.

The key objectives of the research are to: 1) demonstrate resonant coupling of phonon polaritons in gallium arsenide to enable high-performance infrared detection, 2) utilize phonon polaritons in epitaxial oxides to enable infrared photodetection at other wavelengths, and 3) integrate van der Waals materials with semiconductor active regions to enhance phonon polariton-based detection. The research aims to realize infrared photodetectors with improved noise performance that can operate at higher temperatures, increasing the scalability of infrared technologies for environmental monitoring, atmospheric sensing, and other applications. The research will also engage rural Iowa communities through educational outreach activities.
