Nanoscale to bulk

Thermal conductivity of nanoscale thin films


  • SSTR is ideal for your thin film thermal conductivity testing needs.
  • In addition to measurements of bulk wafers and substrates (source 1, source 2), SSTR has the unprecedented spatial resolution to measure the thermal conductivity of thin films.
  • For example, SSTR can measure the thermal conductivity of single nanometer thick ALD grown thin films or micron thick AlN films (source).
