The Morphology and Optical Properties of ZnO Nanorods Grown on MoS2 Thin Films at Various Thicknesses Using a Chemical Bath Deposition Method

2D–1D mixed-dimensional heterostructures: progress, device applications and perspectives

“…Light will pass the transparent monolayer graphene and be confined at the heterointerface, leading to enhancement of absorption as well as facilitation of carrier transfer. Similar characteristic was demonstrated in MoS 2 -ZnO NRs [54], which has a wider absorption range from 350 to 800 nm and stronger absorption compared with single components. These structures with light trapping effect have great potentials for optoelectronics such as solar cells and photodetectors.…”

“…For example, Zhang et al demonstrated the growth of ZnO NRs on graphene without 'seed' layer [55]. The as-prepared graphene is face-down immersed into solution containing zinc nitrate hexahydrate and surfactant, and then the vertical ZnO NRs with diameter of 250 nm can be obtained after 4 h at 90 • C. Similar method is also reported in MoS 2 -ZnO NRs heterostructures [52][53][54], which can be achieved by heating a mixture of MoS 2 and zinc nitrate hexahydrate in autoclave for 4 h at 90 • C. Compared with twostep vapor method, although the hydro-/solvothermal strategy is very sensitive to experimental condition, the advantages of easy operation and large yield, making it an alternative option for constructing 2D-1D heterostructures.…”

“…Owing to the merits of flexibility and controllability, twostep vapor process is recognized as one of the most promising methods in creating 2D-1D heterostructures with clean interface. 2D-1D heterostructures containing metal oxides nanowires have been widely exploited via hydro-/solvothermal routes [52][53][54][55]. For example, Zhang et al demonstrated the growth of ZnO NRs on graphene without 'seed' layer [55].…”
