Claim 0:
1. A method of patterning a two-dimensional (2D) material layer, the method comprising:
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;
forming a 2D material layer including a 2D material at in both the first region and the second region, wherein an adhesive force between the 2D material and the first material layer in the first region is greater than an adhesive force between the 2D material and a separate material in the second region; and
removing the 2D material layer from the second region based on using a physical removal method and not removing the 2D material layer from the first region, such that the 2D material layer remains exclusively in the first region, based on the adhesive force between the 2D material and the first material layer in the first region being greater than the adhesive force between the 2D material and the separate material in the second region.
