Abstract The dynamic regulation of thermal radiation in the mid‐infrared region is technologically important in diverse applications such as thermal management and camouflage. However, there is a notable lack of research on the combination of infrared radiators and memristors, which can maintain previous states or modes without extra power consumption. Here, a memristive mid‐infrared radiator, where graphene nanoribbon grating serves simultaneously as a floating gate for charge storage and a tunable infrared nanoantenna for thermal radiation is proposed. This design enables precise and fast modulation, low power consumption, and scalability. Even a small change of one attocoulomb in the stored charge can produce a 1‐µm peak shift in the absorption peak. This work provides a platform for a memristive infrared thermal radiator that can be further exploited for electrochromic glazing or on‐chip radiative cooling. |
