제목 Large Scale Growth of Vertically Standing MoS2 Flakes on 2D Nanosheet using Organic Promoter
초록 A facile method was demonstrated for conventional thermal chemical vapor deposition (TCVD) growth of large-scale vertically standing molybdenum disulfide nanoflakes on a basal MoS2 thin film (v-MoS2 on MoS2-TF) using an organic seeding promoter layer, which catalyzed the synthesis and allowed large scale growth of v-MoS2 on MoS2-TF. We propose that vertical MoS2 nanoflakes are formed by the bubbling effect of an organic promoter used during the CVD process. Herein, the growing density of the vertical MoS2 flakes was controlled by adjusting the growth temperature and the thickness of the organic promoter layers. Additionally, the vertically grown MoS2 shows applicability as the catalyst for hydrogen evolution reaction and the chemical sensor owing to the active sites in a given exposed area.
