Considering the significant influence of trions on the optical and electronic properties of two-dimensional transition metal dichalcogenides, the precise tuning of trions in a large range is important for optoelectronic or trion-related applications. Herein, a detailed comparison of eco-friendly CuInS2 (CIS) quantum dots (QDs) and (Al, Zn) co-doped CIS QDs on tuning the trion ratio and electrical properties in a mechanically-exfoliated monolayer (ML) WS2 is presented. With a similar QD...[Show more]
