利用石墨烯增强圆偏振光探测器性能
Enhancing the Performance of Circularly Polarized Light Detectors Using Graphene
摘要
Abstract
The active layers of CPL(Circularly Polarized Light)detectors are mostly chiral organic materials.In view of the problems such as slow response speed,weak photocurrent,and low discrimination of CPL,the solvent-induced method is used to induce the supramolecular self-assembly of the organic polymer poly(3-hexylthiophene)(P3HT)into a chiral nw(nanowire)structure.The photodetector with chiral nw-P3HT as the active layer can detect CPL,and has a sensitive responsivity to light and good stability,but the photocurrent is small.Graphene is used as a carrier collection device to optimize the device structure,effectively improving the performance of the CPL detector.The introduction of graphene increases the photocurrent of the CPL detector by five orders of magnitude,shortens the rise time by 16%,and shortens the fall time by 20%.The discrimination ability of the detector with graphene as the carrier collection device for CPL is increased by 30%.The strategy of using graphene to enhance the CPL detector has potential application values in optical imaging and optical sensors.关键词
