Herein, benefiting from anneasy solution process, high light absorption coefficient, and widenabsorption range, environment-friendly CuInSe&lt;sub&gt;2&lt;/sub&gt; quantumndots (QDs) are hybridized with monolayer MoS&lt;sub&gt;2&lt;/sub&gt; for high-performancenbroadband photodetectors. Owing to the favorable type-II energy bandnalignment of MoS&lt;sub&gt;2&lt;/sub&gt;/CuInSe&lt;sub&gt;2&lt;/sub&gt;-QDs, the hybrid photodetectornexhibits a broadband photoresponse from the ultraviolet to near-infrarednregion, with an ultrahigh photoresponsivity of 74.8 A/W at 1064 nm,nand compared with those of the pristine MoS&lt;sub&gt;2&lt;/sub&gt; device, thenphotoresponsivity and specific detectivity in the ultraviolet–visiblenregion were enhanced by about 30 and 20 times, respectively. Furthermore,nthe formed depletion region at the MoS&lt;sub&gt;2&lt;/sub&gt;/CuInSe&lt;sub&gt;2&lt;/sub&gt;-QDs interface can significantly increase the photoresponse speed,nand the accumulated holes in the QD side induce a strong photogatingneffect to improve the photoresponsive characteristics of the hybridnphotodetector. Our work opens up opportunities for fabricating high-performancenmonolayer TMD-based broadband photodetectors.","PeriodicalId":522951,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
