Abstract

In this study, we present the study of van der Waal (vdW) hybrid structure of zero-dimensional graphene quantum dots (GQDs) and fullerene (C60) in conjunction with two-dimensional molybdenum disulphide (MoS2) and tungsten diselenide (WSe2) semiconducting transition metal dichalcogenides (TMDs). The vdW hybrid structures were characterized by Raman and photoluminescence (PL) spectroscopy which have revealed n-type doping occurring in MoS2 after decoration of GQDs, and a p-type doping occurring in WSe2 after decoration of C60. After outlining the fabrication of our 0D-2D heterostructure photodetectors, their photo response to incoming radiation was measured using broadband illumination which has revealed a two-fold increase in photo response in MoS2 and a three-fold increase in WSe2 after decoration with GQDs and C60, respectively. Our results presented here provide insights into 2D and 0D-based hybrid structures, thus enabling platform for high-performance photodetectors.
利用吸收光的碳基零维量子点增强MoS2和WSe2杂化材料的光电导率
在这项研究中,我们提出了零维石墨烯量子点(GQDs)和富勒烯(C60)结合二维二硫化钼(MoS2)和二硒化钨(WSe2)半导体过渡金属二硫化物(TMDs)的范德华(vdW)杂化结构的研究。利用拉曼光谱和光致发光光谱(PL)对vdW杂化结构进行了表征,发现GQDs修饰后MoS2中出现了n型掺杂,C60修饰后WSe2中出现了p型掺杂。在概述了我们的0D-2D异质结构光电探测器的制作之后,我们使用宽带照明测量了它们对入射辐射的光响应,结果表明,在用GQDs和C60装饰后,MoS2和WSe2的光响应分别增加了两倍和三倍。我们在这里提出的结果提供了对基于2D和0d的混合结构的见解,从而为高性能光电探测器提供了平台。
