The fabrication of ReS2 flowers at controlled locations by chemical vapor deposition

Here we report a metal induced nucleation to realize the growth of ReS2 flowers at controlled locations. The ordered arrays of ReS2 flowers have been successfully prepared on SiO2/Si substrate using Pt metal dots as nucleation sites and S, NH4ReO4 powders as precursors by a chemical vapor depostion method. The NH4ReO4 powders are used as the rhenium sources. The ReS2 flowers are grown above the pre-patterned Pt dots, Raman and transmission electron microscopy measurements indicated that the prepared ReS2 flowers have excellent crystalline quality.
