摘要
利用石墨烯设计表面等离子体共振太阳能吸收器,以研究光子设备的太阳能吸收器。根据该结构中每种金属各自的特性,钨(W)层用作地层,铬(Cr)用于创建谐振器设计,氮化钛(TiN)基底层分别构建在铬层和 W 层之间。根据石墨烯在制作吸收器方面的优势,还在 TiN 的上方和 Cr 谐振器设计的下方构建了一层石墨烯薄膜。为了显示光谱(紫外线和近红外之间)的辐射效应,选取了四个最高波长(以微米为单位),如 0.4、1.6、1.8 和 2。根据波段范围,输出吸收率在 0.7 微米处分别为 97.2%,在 1.730 微米处为 95.35%,在 2.8 微米处为 90.15%。在太阳能吸收器表演中,提取吸收率之前的第一件大事是设计构造,我们为每种构造提出了几个阶段的输出,以实现最后(完整)的步骤。在探索了设计中每个现有层的设计和厚度后,我们可以改变每个层(谐振器、基板和地面)中已探索厚度的下方和上方参数。这种变化还可以通过相应的彩色图来显示不同颜色的输出辐射。在设计中吸收百分比的计算部分,还介绍了空气质量(AM)和石墨烯方程,并对每个符号进行了解释。建议的太阳形状设计可用于热处理,如水加热系统。
Graphene-Based Surface Plasmon Resonance–Based Solar Thermal Absorber Using Cr-TiN-W Multilayer Structure
The design of surface plasmon resonance solar absorbers with graphene is demonstrated to study the solar absorbers of photonic devices. With the respective properties of each metal in this structure, the tungsten (W) layer is performed as a ground layer, chromium (Cr) is used to create the resonator design, and the titanium nitride (TiN) substrate layer is constructed between Cr and W layers, respectively. According to the advantages of graphene in making absorbers, a thin film of graphene is also constructed above TiN and below the Cr resonator design. To show the radiation effects in spectrums (between UV and NIR), the four highest wavelength numbers (in micrometers) are picked such as 0.4, 1.6, 1.8, and 2. According to the band range, the output absorption observes 97.2% at 0.7 µm, 95.35% at 1.730 µm, and 90.15% at 2.8 µm, respectively. In solar absorber performing, the first important thing before extracting the absorption rate is design construction, and we presented several stages of outputs for each construction to bring the final (complete) step. After exploring the design and thickness of each existing layer in the design, we can change the below and above parameters of the explored thickness in each layer (resonator, substrate, and ground). The variation can also be demonstrated in respective color plots to show the output radiation in different colors. In the calculating section of the absorption percentage in design, the air mass (AM) and graphene equations are also presented with the explanation of each symbol. The proposed sun-shaped design can be used in performing thermal processes such as water heating systems.
期刊介绍:
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
