"Large area, few-layer graphene films on arbitrary substrates by chemical vapor deposition," by Alfonso Reina and 7 others, Nano Letters, 9(1): 30-5, January 2009.

[Authors' affiliation: MIT, Cambridge, MA]

Abstract: "In this work we present a low cost and scalable technique, via ambient pressure chemical vapor deposition (CVD) on polycrystalline Ni films, to fabricate large area (similar to cm(2)) films of single- to few-layer graphene and to transfer the films to nonspecific substrates. These films consist of regions of 1 to similar to 12 graphene layers. Single- or bilayer regions can be up to 20 mu m in lateral size. The films are continuous over the entire area and can be patterned lithographically or by prepatterning the underlying Ni film. The transparency, conductivity, and ambipolar transfer characteristics of the films suggest their potential as another materials candidate for electronics and opto-electronic applications."
This 2009 report from Nano Letters was cited 40 times in current journal articles indexed by Clarivate Analytics during July-August 2010. Only one other chemistry paper published in the last two years, aside from reviews, attracted a higher citation total during that two-month period. It is one of six reports on graphene that currently occupy the top rungs of chemistry’s ten most-cited papers.

Prior to the most recent bimonthly count, citations to the paper have accrued as follows:

March-April 2010: 34 citations
