Recently, two-dimensional transition metal dichalcogenides (TMDCs) materials have been widely studied due to their unique electrical, optical, and mechanical properties. Tuning the electronic properties of TMDCs is essential for improving transistor performance in nanoelectronics devices. In this study, we demonstrate the effect of polymer doping on TMDCs monolayer by using density functional theory calculations. Our results show that after polymer doping the width of the band gap of TMDCs monolayer decreases significantly compared to without polymer doping. The results can be explained through analysis of the density of state of the monolayer.
