| Research Abstract |
We intend to measure the mean free paths of phonons and electrons by using micro-machined Si thin films with micro-holes. The thermal conductivities of the micro-structured Silicon were measured, and the measured values can be explained by the classical transport model. The mean free path of phonons is calculated to be about 3um by Fucks-Sondheimer model, and it is longer than that of electrons.
