Weatherup, RS and Baehtz, C and Dlubak, B and Bayer, BC and Kidambi, PR and Blume, R and Schloegl, R and Hofmann, S (2013) Introducing Carbon Diffusion Barriers for Uniform, High Quality Graphene Growth from Solid Sources. Nano Lett.Full text not available from this repository.
Carbon diffusion barriers are introduced as a general and simple method to prevent premature carbon dissolution and thereby to significantly improve graphene formation from the catalytic transformation of solid carbon sources. A thin Al2O3 barrier inserted into an amorphous-C/Ni bilayer stack is demonstrated to enable growth of uniform monolayer graphene at 600°C, with domain sizes exceeding 50 μm, and an average Raman D/G ratio of <0.07. A detailed growth rationale is established via in situ measurements, relevant to solid-state growth of a wide range of layered materials, as well as layer-by-layer control in these systems.
