“…Any actual macroscopic thermal body cannot emit more thermal radiation than a blackbody. The Stefan-Boltzman law provides an important theoretical foundation for much of the recent works aiming to design nanophotonic structures in order to tailor the spatial and spectral properties of far-field thermal emission [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] .…”

The control of thermal radiation is of great current importance for applications such as energy conversions and radiative cooling. Here we show theoretically that the thermal emission of a finite-size blackbody emitter can be enhanced in a thermal extraction scheme, where one places the emitter in optical contact with an extraction device consisting of a transparent object, as long as both the emitter and the extraction device have an internal density of state higher than vacuum, and the extraction device has an area larger than the emitter and moreover has a geometry that enables light extraction. As an experimental demonstration of the thermal extraction scheme, we observe a four-fold enhancement of the far-field thermal emission of a carbon-black emitter having an emissivity of 0.85.

Abstract:The optical properties of one-dimensional photonic crystals with Er 2 O 3 /Si structure are designed and calculated by Finite-Difference Time-Domain method. The influence of different thickness and reflectivity on the radiation properties were studied. It was found that the radiation spectral intensity at high temperatures was drastically reduced near the wavelength of 1.8 μm for a 40% Er 2 O 3 + 60% Al 2 O 3 sample due to the strong oscillations of the reflectance.

“…However, the emissive and absorptive properties of these devices often need to be modified to fulfill particular application requirements-such as gas species selectivity. Several solutions have been proposed including "black" coatings, 11,12 and quarter-wavelength structures, 13,14 in addition to plasmonic [15][16][17][18][19][20] and photonic crystal structures. [21][22][23][24][25] In this paper, we report on a reproducible post-process based on micro-inkjet deposition of graphitic carbon nanomaterial adlayers to augment the IR emissivity of fully CMOS compatible micro-electro-mechanical IR light sources, which we have theoretically and experimentally investigated.…”

In this paper, we demonstrate a micro-inkjet printing technique as a reproducible post-process for the deposition of carbon nanoparticles and fullerene adlayers onto fully CMOS compatible micro-electro-mechanical silicon-on-insulator infrared (IR) light sources to enhance their infrared emission. We show experimentally a significant increase in the infrared emission efficiency of the coated emitters. We numerically validate these findings with models suggesting a dominant performance increase for wavelengths <5.5 μm. Here, the bimodal size distribution in the diameter of the carbon nanoparticles, relative to the fullerenes, is an effective mediator towards topologically enhanced emittance of our miniaturised emitters. A 90% improvement in IR emission power density has been shown which we have rationalised with an increase in the mean thickness of the deposited carbon nanoparticle adlayer.
