    • Lattice thermal conductivity of a silicon nanowire under surface stress 

      Liangruksa, Monrudee; Puri, Ishwar K. (American Institute of Physics, 2011-06-01)
      The effects of surface stress on the lattice thermal conductivity are investigated for a silicon nanowire. A phonon dispersion relation is derived based on a continuum approach for a nanowire under surface stress. The ...
    • Phonon transport in an initially twisted polyvinyl acetate nanofiber 

      Liangruksa, Monrudee; Puri, Ishwar K. (AIP Publishing, 2013-05-01)
      A reduction in phonon thermal conductivity enhances thermoelectric performance. One method to accomplish this is by applying mechanical stress to a nanostructure. We consider an initially twisted 20 nm polyvinyl acetate ...
