Disclosed are an electronic device including a two-dimensional material, and a method of fabricating the electronic device. The electronic device may include a first metal layer including a transition metal, a second metal layer on the first metal layer and including gold (Au), and a two-dimensional material layer between the first metal layer and the second metal layer. The two-dimensional material layer may include a transition metal dichalcogenide (TMD). The two-dimensional material layer may be formed as a chalcogen element diffuses into the second metal layer and reacts with the transition metal of the first metal layer adjacent to the second metal layer.

A semiconductor device according to an embodiment may include a substrate, an adhesive layer, and a semiconductor layer. The semiconductor layer includes a 2D material having a layered structure. The adhesive layer is interposed between the substrate and the semiconductor layer, and has adhesiveness to a 2D material.

Semiconductor device including two-dimensional material

A method of forming graphene includes: preparing a substrate in a reaction chamber; performing a first growth process of growing a plurality of graphene aggregates apart from each other on the substrate at a first growth rate by using a reaction gas including a carbon source; and performing a second growth process of forming a graphene layer by growing the plurality of graphene aggregates at a second growth rate slower than the first growth rate by using the reaction gas including the carbon source.

Method of forming graphene

A method of patterning a 2D material layer is includes selectively forming a first material layer on a surface of a substrate to form a first region in which the first material layer covers the surface of the substrate and to further form a second region in which the surface of the substrate is exposed from the first material layer, the first material layer having a strong adhesive force with a 2D material. The method further includes forming a 2D material layer is formed in both the first region and the second region. The method further includes selectively removing the 2D material layer from the second region based on using a physical removal method, such that the 2D material layer remains in the first region.
