CHRoMIC's ambition is to implement a set of numerical methods capable of accurately and efficiently determining the infrared emissivity of semiconductor materials through the calculation of their dielectric functions. The selenium element will serve as a model material given the possibility of obtaining it under different allotropic varieties by thin-film deposition, to modify its crystallization state and to measure the impact of the previous parameters on the infrared emissivity. Two major conceptual challenges will be tackled: the precise identification and quantification of all the absorption mechanisms taking shape at the atomic scale in the infrared domain by ab initio simulations of the dielectric function from computation codes based on density functional theory (DFT), and taking into account the impact of microstructural complexity on emissivity via homogenization methods through a numerical implementation to process real size samples . CHROMIC, thanks to its general and fundamental nature, will be able to open up the search for new materials with spectrally adjustable emissivities, for applications ranging from building heat (eg smart glazing) to solar-heat conversion at high temperatures (eg absorbers), etc.
