Title: Stable Silicene in Graphene/Silicene Van der Waals Heterostructures

Abstract

Silicene-based van der Waals heterostructures are theoretically predicted to have interesting physical properties, but their experimental fabrication has remained a challenge because of the easy oxidation of silicene in air. Here, the fabrication of graphene/silicene van der Waals heterostructures by silicon intercalation is reported. Density functional theory calculations show weak interactions between graphene and silicene layers, confirming the formation of van der Waals heterostructures. The heterostructures show no observable damage after air exposure for extended periods, indicating good air stability. The I–V characteristics of the vertical graphene/silicene/Ru heterostructures show rectification behavior.

Figure 1 Figure 1: Schematic diagram of the formation of silicene structures at the Graphene/Ru(0001) interface. The deposited Si atoms intercalate between graphene and the Ru substrate during annealing process. With a small Si dosage, Si atoms form honeycomb silicene nano-flakes below the atop regions. With more Si intercalation, Silicene monolayers andmore » multilayers form.« less
