A multilayer structure includes a first material layer, a second material layer, and a diffusion barrier layer. The second material layer is connected to the first material layer. The second material layer is spaced apart from the first material layer. The diffusion barrier layer is between the first material layer and the second material layer. The diffusion barrier layer may include a two-dimensional (2D) material. The 2D material may be a non-graphene-based material, such as a metal chalcogenide-based material having a 2D crystal structure. The first material layer may be a semiconductor or an insulator, and the second material layer may be a conductor. At least a part of the multilayer structure may constitute an interconnection for an electronic device.

Abstract:
Provided are methods of directly growing a carbon material. The method may include a first operation and a second operation. The first operation may include adsorbing carbons onto a substrate by supplying the carbons to the substrate. The second operation may include removing unreacted carbon residues from the substrate after suspending the supplying the carbons of the first operation. The two operations may be repeated until a desired graphene is formed on the substrate. The substrate may be maintained at a temperature less than 700° C. In another embodiment, the method may include forming a carbon layer on a substrate, removing carbons that are not directly adsorbed to the substrate on the carbon layer, and repeating the two operations until desired graphene is formed on the substrate. The forming of the carbon layer includes supplying individual carbons onto the substrate by preparing the individual carbons.
