Graphene provides exceptional properties such as extremely large room-temperature electron mobility, elastic constant, breaking strength, and a transparency of 97%, which has high potential for applications. In fact, strong efforts are being made to realize displays based on graphene as a transparent electrode. High-frequency transistors that take advantage of the large mobility of graphene are under way, same as are tunable optical absorbers that make use of the linear band structure of the material. Even graphene in combination with textiles as an alternative for batteries is intensely investigated due to the fact that graphene is surface only.

In his Feature Article (pp. 2423-2434), Markus Morgenstern summarizes the most important findings on the electronic properties down to the atomic scale that were obtained by scanning tunneling microscopy.

The cover image shows graphene with atomic resolution as measured by STM with an artificial STM tip on top. Two screens are attached to the STM tip. The left is showing a mechanically manipulated graphene area and the right the spectroscopic result in magnetic field, i.e. Landau levels.
