| Outline of Annual Research Achievements |
In FY 2023, the contributions of atomic surface terminations to phonon transmission across a nanogap and mechanism of excessive local heat flux at interfacial layers were studied by molecular dynamics simulations using LAMMPS. For SiC-SiC nanogap, the optical phonon transmission enhanced heat transfer across SiC-SiC nanogap in the identical case of C-C with thermal resonance between C-terminated layers. For Pt-water interface, a singular excess in local heat flux appears only at resonant interfacial layers, whereas a uniform distribution is noted without interfacial resonance.
These results have been published in Nanoscale by Royal Society of Chemistry and presented at 14th International Conference on Computational Heat and Mass transfer and Thermal Engineering Conference 2023.
