Abstract: G70.00331 : Nonequilibrium Landauer approach for thermal interfaces
(University of California, Los Angeles)
temperature for each individual mode is not their emitting temperature, and due to the nonuniform transmission functions, different phonon modes are driven into strong thermal nonequilibrium. Hence, we modify the Landauer approach to include these effects and name it the
”Nonequilibrium Landauer approach”. Using our approach on the Al/Si and ZnO/GaN interfaces gives 100% increases in TBC as compared to the original Landauer approach and can now well explain the experimental results.
