Abstract
Described is a composite material composed of an atomically thin (single layer) amorphous carbon disposed on top of a substrate (metal, glass, oxides) and methods of growing and differentiating stem cells.
Claims6
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.
