“…There are several lithography-free approaches for fabricating structures with light absorption properties. One of the most notable is based on the Tamm plasmon polaritons supported by a thin metal film on a multi-layer Bragg reflector stack [ 29 , 30 , 31 , 32 , 33 ]. Other useful materials include so-called black metals or plasmon super absorbers [ 33 , 34 , 35 , 36 , 37 ], which are comprised of a metal ground plate and a thin overlaying semiconductor film [ 28 , 36 , 38 ].…”

Lithography-free black metals composed of a nano-layered stack of materials are attractive not only due to their optical properties but also by virtue of fabrication simplicity and the cost reduction of devices based on such structures. We demonstrate multi-layer black metal layered structures with engineered electromagnetic absorption in the mid-infrared (MIR) wavelength range. Characterization of thin SiO2 and Si films sandwiched between two Au layers by way of experimental electromagnetic radiation absorption and thermal radiation emission measurements as well as finite difference time domain (FDTD) numerical simulations is presented. Comparison of experimental and simulation data derived optical properties of multi-layer black metals provide guidelines for absorber/emitter structure design and potential applications. In addition, relatively simple lithography-free multi-layer structures are shown to exhibit absorber/emitter performance that is on par with what is reported in the literature for considerably more elaborate nano/micro-scale patterned metasurfaces.

“…Although a similar idea has been suggested to construct narrowband thermal emitters, 34,35 to the best of our knowledge, few real prototype samples operating in the MIR wavelength range (especially in the long-wavelength infrared λ > 8 μm) have been reported. [36][37][38] In this study, a 200 nm thick gold (Au) film was deposited on a polished silicon wafer after deposition of a 10 nm thick chromium (Cr) adhesion layer. A 298 nm thick zinc sulfide (ZnS) layer was then deposited by electron-beam (E-beam) evaporation and functioned as a dielectric spacer.…”

“…One pair case shows the optimized result with Q ‐factor = 6.43 for the TiN TPP in the simulation. To improve the Q ‐factor of a TPP structure, metallic materials,49 metal thicknesses,41 and the thickness of d last layer to support hybrid mode resonance50,51 have been investigated. However, little discussion was made focusing on adjusting the DBR's stop band by changing the dielectric layer on the superstrate side.…”

generation, [4][5][6] radiative cooling, [7] and thermophotovoltaics (TPVs). [8] When selective thermal emitters are intended to emit in shorter mid IR range (e.g., an emitter for TPV system), the emitter has to be heated above one thousand kelvin. [9] Refractory metals such as molybdenum (Mo) [10] and tungsten (W) [11] are required in such cases. However, searching for alternative plasmonic materials is essential for reducing the material cost as well as for material research interest.Transition metal nitrides such as titanium nitride (TiN) and zirconium nitride (ZrN) also possess melting point as high as ≈3000 °C, [12][13][14] hence regarded as good candidate materials for thermal emitters. In addition, transition metal nitrides are regarded as alternative plasmonic materials in the visible to infrared region due to their high carrier concentrations up to 10 21 -10 22 cm −3 . [15] Among transition metal nitrides, TiN receives many attentions as an alternative plasmonic material in the past decades. [16][17][18] One of the advantages of using TiN is that it can be used in much higher temperature than other plasmonic materials. [19][20][21] However, there are only limited studies on thermal emitters using TiN so far.To demonstrate wavelength selective thermal emission, nanostructures have been investigated intensively [22,23] rather than microcavity structures which have been studied in 1990's and early 2000's. [24][25][26] Variety of nanostructures have been proposed, such as 1D grating, [27,28] 2D or 3D metallic photonic crystals, [2,29,30] and metal-insulator-metal (MIM) metamaterial structures. [31] Among those nanostructures, MIM metamaterial structures are easy to achieve wavelength selective emissions with single or multibands whose bandwidths and emission wavelengths are adjustable. [32] However, the requirement of nanofabrication, such as e-beam lithography, leads to limitations in large area fabrications.In contrast, thin-film based devices are the candidates for large area samples which do not require nanopatterning. [33,34] One way to optimize 1D thin film structures is via manipulating the phase-shifting layers in Gires-Tournois resonator. [35] Several different multilayer thin-film designs have been explored, which include Fabry-Perot cavity with either distributed Bragg reflectors (DBRs) and/or metallic mirror(s) and Tamm plasmon polaritons (TPPs) structures. For MIM structures (i.e., Fabry-Perot cavity), standing waves exist within the dielectric layer to form a cavity resonator. [36][37][38] In contrast, 1D TPP structure can excite TPP resonance at the interface of a A refractory wavelength selective thermal emitter is experimentally realized by the excitation of Tamm plasmon polaritons (TPPs) between a titanium nitride (TiN) thin film and a distributed Bragg reflector (DBR). The absorptance reaches nearly unity at ≈3.73 μm with the bandwidth of 0.36 μm in the experiment. High temperature stabilities are confirmed up to 500 and 1000 °C in ambient and in vacuum, respectively. When the TiN TPP stru...
