论文摘要
我们提出了一个热电设备，即使在均匀温度的环境中，也可以产生热梯度。我们引入了一个超材料吸收器（MA），该吸收剂包括一个透明的氟化钙层，该钙夹在银色镜层和银微电池阵列之间，这是由二胰物质剂制成的热电设备的一端。 MA的加热效率和设备的相对电极不平衡。因此，引起了塞贝克效应，导致发电。我们在装有热电设备上的铜电极上制造了MA，并将设备放置在364 K的均匀温度环境中。实验测量了整个设备上的热梯度，发现为0.14 k。
We propose a thermoelectric device that can produce a thermal gradient even in a uniform-temperature environment. We introduced a metamaterial absorber (MA), which comprised a transparent calcium fluoride layer sandwiched between a silver mirror layer and silver microdisk arrays, at one end of a thermoelectric device made of bismuth antimony telluride. The heating efficiencies of the MA and opposite electrodes of the device were unbalanced; consequently, the Seebeck effect was induced, resulting in electricity generation. We fabricated the MA on a copper electrode loaded on a thermoelectric device, and the device was placed in a uniform-temperature environment at 364 K. The thermal gradient across the device was experimentally measured and was found to be 0.14 K.
