The National Science Foundation (NSF) awarded a 3-year, $352,829 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to the University of Texas at Dallas (UTD) to conduct collaborative research on manipulating the thermal properties of two-dimensional (2D) materials through interface structure and chemistry. The key research objectives are to:
-
Understand and control thermal boundary conductance at 2D-2D and 2D-bulk material interfaces by applying extreme pressure to alter interface structure. This will provide fundamental insights on structure-property relationships for thermal boundary conductance in 2D materials.
-
Identify changes in phonon dispersion and scattering due to interface modifications, which can impact energy transport and conversion in 2D materials.
The project integrates experimental measurements using Raman spectroscopy with first-principles modeling and molecular dynamics simulations. This multifaceted approach aims to enable practical pathways for engineering the thermal properties of 2D materials and mitigating thermal limitations in 2D electronic devices. The award also supports the development of educational programs for underrepresented students and new artwork conservation programs using optical techniques.
