Proposed are a two-dimensional vertical composite laminate including graphene and hexagonal boron nitride and a method of fabricating the same. The composite laminate includes a first layer and a second layer positioned on the first layer, in which the first layer includes a first boron nitride layer containing hexagonal boron nitride or a first graphene layer containing graphene, and the second layer includes a second boron nitride layer containing hexagonal boron nitride or a second graphene layer containing graphene. The composite laminate allows for the control of the twist angle and stacking order of each layer, so that the composite laminate can have the desired crystal structure, crystal thickness, and composition to exhibit novel physical properties.
