Resumo

Recent years, there has been an increased interest to the conception of micro/nanostructures with unusual radiative properties, especially thermal sources with temporal and/or spatial coherent emission. Such structures are indeed extremely interesting for energy conversion systems, radiative cooling devices,... The present study investigate numerically temporal coherent emission from a very simple structure composed with one stack of germanium and one of silicon carbide. Our investigation shows that, for well-defined thicknesses, this two-stack structure is able to emit in narrow spectral peak.
