“…2 Blackbody radiation is a conventional light source for infrared thermal emitter and the wavelength emitted can be controlled by modifying the surface structure. Many schemes have been demonstrated to create a polarized thermal emitter, such as onedimensional ͑1D͒ metallic grating, 3 metallic gutters, 4 and 1D silicide grating. 5 Conventionally, thermal radiation was generated then coupled with the artificial surface structure mediated by surface plasmon ͑SP͒ polariton, 3 or surface phonon polariton.…”

Polarized infrared thermal emitters consisting of a waveguide thermal emitter combined with silver grating structure were studied. For a device containing a perforated silver film under the grating, polarized infrared light was emitted only when the wavelength satisfied the standing wave condition, therefore the broad bandwidth SiO2 phonon vibration modes were suppressed in the thermal radiation spectrum. The polarized ratio with different grating thickness was investigated and the highly polarized ratio up to 0.875 was achieved. This study demonstrated that the integrated structure can be used as a narrow bandwidth and highly polarized ratio infrared light source.

“…The radiation characteristics of the different micro-structured surfaces have been theoretically [4][5][6][7][8][9] and experimentally [10][11][12] investigated by a number of researchers to improve the spectral features of solar cell surfaces. When the materials and the micro-structural characteristics of solar cells are in a certain relation, the surface plasmon polaritons will be excited and the absorption of sunlight will be enhanced, which will remarkably improve the conversion efficiency.…”

The temperature of a solar cell will increase when it is exposed to the sunlight, which results in variations of optical parameters and thermal expansion coefficient of the cell, thus affecting its spectral absorption feature. This paper is aimed to investigate the effects of temperature on the absorption property of solar cells with micro-structured surfaces. By taking hemispherical, cylindrical and spherical surfaces as models, numerical computation is conducted to obtain spectral distribution of absorptance of such surfaces with different structural parameters by means of the finite difference time domain (FDTD) method. Furthermore, the effects of material properties and structural period on the absorption property are also investigated. temperature, dielectric function, thermal expansion coefficient, absorption property Citation: Yang L L, Xuan Y M, Han Y G, et al.

“…Recently, patterns in gold and various other metals have become necessary and three-dimensional (3D) metal patterns are also desired for plasmon photonics and optical devices. For example, a high aspect ratio grating structure on a gold surface is used for creating a thermal emission source of linearly polarized and narrow-band midinfrared waves (1) , and silver nanorods are used for a metallic nanolens to observe subwavelength color images (2) . Moreover, copper fine patterns are used for LSI wiring because of their low resistivity and low cost.…”

There is a strong need for a fine three-dimensional metal patterning technique for fabricating next-generation devices such as patterned media and plasmon photonic and nano-scale electrodes. In addition, flexible and transparent electronic devices on plastic substrates are desired for wearable devices and flexible thin-film displays. Therefore, a technique for patterning metals onto plastic substrates is required. Nanotransfer printing (nTP) has received much attention recently because of its high throughput and high resolution compared to inkjet printing. However, it is difficult to create sub-100 nm metal patterns using nTP because the PDMS stamp is deformed by transfer pressure. Therefore, we have developed a technique for transferring three-dimensional metal patterns onto a polyethylene terephthalate (PET) substrate by nanoimprint lithography using a metal oxide release layer. The three-dimensional nanoimprint mold was fabricated by control of acceleration voltage electron beam lithography (CAV-EBL) with spin-on-glass (SOG). As a result, three-dimensional metal nano patterns were obtained using a metal oxide release layer. Moreover, the metal moth-eye structure, which has a very high aspect ratio, was transferred onto a PET substrate by applying our process to the moth-eye structure on glassy carbon.
