Based on the previous studies, an IR light source can be made harnessing selected molecular vibration and it has a high potential for miniaturisation of IR optical sensors. However, when organic molecules are used, heat resistance of polymer restricts range of temperatures at which MIM structure can be used. For example, even polyimide, a well-known heat-resistant polymer material, starts to decompose at temperatures above 350 • C, reducing potential use of such metasurface as temperature driven black-body emitter. According to the Stefan-Boltzmann law, the total radiant power emitted from a surface is proportional to ∝ T 4 while the maximum wavelength of emission is blue-shifted with temperature ∝ 1/T (Wien's law).
