Goals:

  • Fundamental Physics: Separate the effects of coherent and incoherent phonon scattering in nanostructures, including periodically porous films.

  • Experimental: Develop fabrication technique and metrology platform to conclusively determine the impact of nanostructures on the order of the phonon mean free path.

  • Theory and Modeling: Develop models to understand and predict the properties for arbitrary materials.

Target Applications:

  • Thermoelectrics

  • Thermal insulation

  • Thermal diodes and rectifiers
