The National Science Foundation (NSF) awarded a $359,971 project grant to the University of Oklahoma to research methods for enhancing heat transfer across the interface between diamond substrates and gallium nitride (GaN) electronic devices. The project, funded under NSF's Engineering program (CFDA 47.041), aims to explore how evanescent electric fields can be leveraged to improve acoustic phonon transmission and thermal conductance at these critical interfaces. This work seeks to enable more effective cooling of high power GaN devices used in applications like laptops, mobile phones, and other electronics. The project will engage graduate and undergraduate students, as well as introduce high school and underrepresented students to the research activities through outreach programs. The award period is from January 15, 2024 to December 31, 2026.
