Abstract
The size effect on thermal transport property due to phonon boundary scattering was studied as controlling heat conduction and "thermal rectifier". We discussed on the thermal rectification effect from the calculation and measurement of asymmetric structured Si membranes. Heat conduction was calculated by using radiation calculation of ANSYS Fluent based on Boltzmann transport theory which is development of equation of phonon radiative transfer. And we measured temperature distribution of micro porous Si membrane by using infrared thermometry system which enabled microscopic measurement.
