Emissivity Measurements and Modeling of Silicon-Related Materials: An Overview

An overview of the emissivity measurements and modeling of silicon-related materials is preseInted.The experimental component of this investigation is based on results obtained utilizing spectral emissometry.An analysis of the comparison of the measured data with other similar approaches is made.In particular, the celebrated work of Sato is revisited to understand the implications of his study.Simulations of the temperature and wavelength dependent emissivity of silicon based on the semiempirical MULTIRAD model are preseInted. The influence of doping concentration, surface roughness, and coatings on the emissivity of silicon, as a function of temperature, is discussed.
