Techniques that give anisotropic properties to 2D materials with isotropic crystal structures will enable 2D material based photodetectors to possess polarization sensitivity in the detection of polarization, which will greatly improve the spatial resolution of photodetectors. Here, an MoS₂‐based polarization photodetector induced by anisotropic plasmonic nanostructure is prepared. The integrating anisotropic plasmonic structures on a few‐layer MoS₂ nanosheet can induce polarization photoresponse and enhance the responsivity of MoS₂ device at the same time. The ratio of the maximum to minimum photocurrents reached 1.45 along two perpendicular polarizations. It proves that anisotropic nanostructure induced polarization sensitivity will pave a new way for the fabrication of polarization photodetectors.

基于MoS2的光电探测器的各向异性等离子纳米结构诱导的偏振光响应

为具有各向同性晶体结构的2D材料赋予各向异性特性的技术将使基于2D材料的光电探测器在偏振检测中具有偏振灵敏度，这将大大提高光电探测器的空间分辨率。在这里，制备了由各向异性等离子体纳米结构诱导的基于MoS ₂的偏振光电探测器。在几层MoS ₂纳米片上集成各向异性等离子结构可以诱导偏振光响应并增强MoS ₂的响应性设备在同一时间。沿着两个垂直极化，最大和最小光电流之比达到1.45。证明了各向异性纳米结构引起的极化灵敏度将为极化光电探测器的制造铺平新的道路。
