1. A method of forming, an article comprising:
a substrate; and
a two-dimensional (2D) amorphous carbon film disposed on a surface of the substrate, wherein the 2D amorphous carbon film has a crystallinity in a range of 0.5≤(C)≤0.8 and is homogenous, the method comprising:
decomposing a precursor gas to generate at least one decomposed species by photolytic decomposition; and
forming the 2D amorphous carbon film from the at least one decomposed species on a surface of the substrate,
wherein the precursor gas comprises a hydrocarbon as a precursor.
