Enhanced energy transport by surface polaritons – EPOLARITON
The main objective of this project is to experimentally demonstrate the polarition thermal conductivity enhancement by means of the 3w and modulated laser beam techniques, which are two accurate methods to measure the in-plane thermal conductivity of thin films. All measurements will be done for nanofilms of SiO2, SiC, Ag, and Cu with different thicknesses smaller than 200 nm. The expected higher thermal conductivity for thinner and/or hotter films will unambiguously demonstrate the existence and energy of polaritons, which could be used to dissipate heat and prevent the overheating of the every time thinner and faster electronic devices. This major breakthrough for lowering the temperature will be confirmed by monitoring and comparing the temperatures of a bare chip placed on top of a substrate with and without a nanofilm, and heated up with a laser beam of different intensities.
