  This review examines the properties of graphene from an experimental
perspective. The intent is to review the most important experimental results at
a level of detail appropriate for new graduate students who are interested in a
general overview of the fascinating properties of graphene. While some
introductory theoretical concepts are provided, including a discussion of the
electronic band structure and phonon dispersion, the main emphasis is on
describing relevant experiments and important results as well as some of the
novel applications of graphene. In particular, this review covers graphene
synthesis and characterization, field-effect behavior, electronic transport
properties, magneto-transport, integer and fractional quantum Hall effects,
mechanical properties, transistors, optoelectronics, graphene-based sensors,
and biosensors. This approach attempts to highlight both the means by which the
current understanding of graphene has come about and some tools for future
contributions.
