WebThe emissivity of silicon was observed in the spectral region from 0.4 to 15 µ at various temperatures from 340°K to 1070°K by using two n-type specimens with the resistivity of 15 ohm-cm and 7 × 10 -3 ohm-cm at 300°K, respectively. The thermal radiation of silicon consists of three types due to band-to-band transition, free carriers and ... WebBy exploiting experimentally measured optical properties of Silicon Carbide (SiC) at different temperatures, we recently showed based on a numerical analysis, that when SiC grating is heated, the position of its emissivity peak shifts towards higher wavelength values and its amplitude decreases. This proved the necessity to adapt the parameters of the …
WebIn the present study, the emissivity of silicon has been investigated. Comparisons of the experimentally measured emissivity have been made with the most celebrated work of Sato [1].Simulations of the wavelength-and temperature-dependent emissivity of silicon, as functions of doping concentration and overlayers, using MULTIRAD [2] are presented. WebNov 23, 2011 · The infrared normal spectral emissivity of microstructured silicon prepared by femtosecond laser was measured for the middle infrared waveband at temperature range 200 to 400°C. Compared to that of flat silicon, emissivity was enhanced over the entire wavelength range. For a sample with different spike height, the max …
