这项工作展示了超材料（MM）选择性热发射器与能量收集光电二极管（如热光伏电池）的潜在用途。利用CST微波工作室和电子束蒸发、原子层沉积和电子束光刻等微加工技术，分别设计、模拟和制造了初步结构。对样品进行了测试，以确定顶层金属厚度对这些器件吸收的影响。还进行了初步的模拟和测试，设计了一个在500°C下工作的装置。
This work demonstrates metamaterial (MM) selective thermal emitters for potential use with energy harvesting photodiodes, such as thermophotovoltaic cells. Preliminary structures have been designed, simulated, and fabricated using CST Microwave Studio and microfabrication techniques including electron beam evaporation, atomic layer deposition, and electron beam lithography, respectively. Samples were tested to determine the effect of top layer metal thickness on the absorption of these devices. Preliminary simulation and testing was also performed to design a device for operation at 500°C.
