论文摘要
扭曲的双层二维电子系统产生了许多外来现象，并推出了研究量子材料的新边界。在光子学中，通过近场相互作用结合的扭曲的二维系统为研究定位和激光提供了一个平台。在这里，我们建议扭曲可以成为调整近场嗜热伏洛伏型系统性能的前所未有的工具。值得注意的是，通过扭曲诱导的光子拓扑转换，我们实现了热伏硫托能效率和功率的显着调整。基本机制与光子等频轮廓从椭圆形变为双曲线几何形状的变化有关，在该设置中，六边形 - 二硝酸盐元素跨表面作为热源，并用作indium andium andium antium andasure $ p $ - $ n $ n $连接。我们发现，在热伏洛尔电系统中可以实现高能源效率，即近53％的carnot效率，而输出功率可以达到$ 1.1 \ times10^4 $ 〜w/m $ $^2 $，而无需源和电池之间的温度差很大。我们的结果表明，扭曲的近场嗜热伏硫托克（Themophotovoltaics）的前途未来，并为可调，高性能的热伏尔抗能和红外检测铺平了道路。
Twisted bilayer two-dimensional electronic systems give rise to many exotic phenomena and unveil a new frontier for the study of quantum materials. In photonics, twisted two-dimensional systems coupled via near-field interactions offer a platform to study localization and lasing. Here, we propose that twisting can be an unprecedented tool to tune the performance of near-field thermophotovoltaic systems. Remarkably, through twisting-induced photonic topological transitions, we achieve significant tuning of the thermophotovoltaic energy efficiency and power. The underlying mechanism is related to the change of the photonic iso-frequency contours from elliptical to hyperbolic geometries in a setup where the hexagonal-boron-nitride metasurface serves as the heat source and the indium antimonide $p$-$n$ junction serves as the cell. We find a notably high energy efficiency, nearly 53\% of the Carnot efficiency, can be achieved in our thermophotovoltaic system, while the output power can reach to $1.1\times10^4$~W/m$^2$ without requiring a large temperature difference between the source and the cell. Our results indicate the promising future of twisted near-field thermophotovoltaics and paves the way towards tunable, high-performance thermophotovoltaics and infrared detection.
