“…Considering this, researchers focused on exploring effective methods to improve the absorption, for example, plasmon enhancement [10,11], waveguide [12,13], and quantum dots [14,15]. However, the desired absorptivity is limited by the narrowband absorption due to the optical characteristics of those structures [16]. Except for low light absorption, the intrinsic TCR of graphene also shows poor superiority, which is −0.05% K −1 only.…”
