Why is Phonon Mismatch Important in Nanotechnology?
As devices shrink to the nanoscale, the surface-to-volume ratio increases dramatically, making surface and interface properties more critical. In nanoscale systems, the thermal conductivity is not only determined by the intrinsic properties of the materials but also by how efficiently phonons can travel across interfaces. Phonon mismatch can lead to increased thermal resistance, impacting the performance and reliability of nanoscale devices like transistors, thermoelectric materials, and quantum dots.
