Radiative cooling: A review of fundamentals, materials

Wu et al. designed VO 2-coated silicon micro-cones for thermal homeostasis (Fig. 33(a)). When the surface temperature is lower than the phase-change temperature of VO 2 (corresponding to its insulating state), the emissivity of the structure is low; otherwise (corresponding to the metallic state of VO 2), the emissivity increases.
