Abstract

In this study heat conduction problems are examined in the microscale domain to ascertain the range of applications where non-Fourier effects are significant and the traditional Fourier heat conduction equation leads to different temperature and heat flux profiles. The values of the thermal relaxation time are compiled for various semiconductors, superconductors, metals, and glass, and analytical and numerical results are obtained for heat conduction temperature profiles for a variety of boundary conditions by using both the Fourier and non-Fourier formulations. It is found that non-Fourier results are significantly different for certain practical applications such as thermally-based thin film superconductor infrared radiation detector whose response is a function of the transient thermal profile in the superconductor film.
