The baseline time span for this database is (publication years)
1998-August 31, 2008 from the fourth bimonthly update (a 10-year + 8-month
period). The resulting database contained 2,777 (10 years) and 1,531 (2
years) papers; 5,804 authors; 65 nations; 348 journals; and 1,320
institutions. See additional paper information below in the overview &

OVERVIEW
The nanomaterial graphene has been attracting a lot of attention over the
past few years, thanks to its unique combination of a simple structure of
bonded carbon atoms with its myriad and complex physical properties. The
potential applications for graphene—as a sensor device, as a
semiconductor, or for components of integrated circuits—have made the
material a hot property. This month, ScienceWatch.com examines the
literature on this innovative material.
The highly cited papers in this topic focus mainly on the structure and
physical properties of various graphene formations. Structures include
nanoribbons, stacks, sheets, and two-dimensional layers. Energy gaps,
splitting, atomic defects, carrier transport, electron-electron
interactions, electron spin transport, ferromagnetism, and semiconducting
abilities are among the physical properties being explored. More recent
papers are focusing on potential applications of graphene, such as
field-effect devices, semiconductors, and electromechanical resonators.
Methodology: The baseline time span for
this database is (publication years) 1998-August 31, 2008 from the
fourth bimonthly update (a 10-year + 8-month period). The resulting
database contained 2,777 (10 years) and 1,531 (2 years) papers; 5,804
authors; 65 nations; 348 journals; and 1,320 institutions.
Papers: To construct the top 20 papers lists for the past
decade and the past two years, the papers were further narrowed down by the
title keywords "graphene." This adjustment resulted in the top 20 papers
being selected from a pool of 637 (10 years) and 525 (2 years) papers.
Rankings: Once the database was in place, it was used to
generate list of authors, journals, institutions, and nations. Rankings for
author, journal, institution, and country are listed in three ways:
according to total cites, total papers, and total cites/paper. The paper
thresholds and corresponding percentages used to determine scientist,
institution, country, and journal rankings according to total cites/paper,
and total papers respectively are as follows:
