LAYER STRUCTURES INCLUDING TWO-DIMENSIONAL CHANNEL LAYER, METHODS OF MANUFACTURING THE SAME, ELECTRONIC DEVICES INCLUDING 2D CHANNEL LAYER, AND ELECTRONIC APPARATUSES INCLUDING ELECTRONIC DEVICE

A layer structure including a two-dimensional (2D) channel layer, a method of manufacturing a two-dimensional (2D) channel layer, an electronic device including the layer structure, and an electronic apparatus including the layer structure are disclosed. The layer structure may include a first substrate, a second substrate surrounded by the first substrate, and a 2D channel layer on the second substrate. An interfacial energy of the second substrate may be less than an interfacial energy of the first substrate. The method of manufacturing a 2D channel layer may include forming a second substrate to be surrounded by a first substrate, forming a precursor layer for forming a 2D channel on any one of the first and second substrates, and transforming the precursor layer into a liquid precursor layer. The interfacial energy of the second substrate may be less than the interfacial energy of the first substrate.
