摘要:

我们探索基于纳米图案化双曲超材料(HMM)的宽带,广角中红外整流,由亚纳米隧道势垒分隔的两种不同的金属组成。由这种周期性沟槽阻碍支持的奇异慢光模式有效地将入射辐射捕获在大规模平行的金属-绝缘体-金属隧道结中,从而支持由光子辅助隧穿引起的超快光学整流。这导致高效的光子到电子转换,比传统的整流天线大几个数量级。我们的研究结果有望对红外能量采集器和等离子体光电探测器产生影响。

英文摘要:

We explore broadband, wide-angle mid-infrared rectification based on nanopatterned hyperbolic metamaterials (HMM), composed of two dissimilar metals separated by a sub-nanometer tunnel barrier. The exotic slow-light modes supported by such periodically trenched HMMs efficiently trap incident radiation in massively parallel metal-insulator-metal tunnel junctions supporting ultrafast optical rectification induced by photon-assisted tunneling. This leads to highly efficient photon-to-electron conversion, orders of magnitude larger than conventional rectennas. Our results promise an impact on infrared energy harvesters and plasmonic photodetectors.
