Introduction

Graphene is a sheet, one-atom-thick of carbon atom, in a honeycomb crystal lattice. If you use many layers of graphene, stacked one on top of the other, you'll get Graphite.

Graphene can be used for many things:

• Sensors, for single molecules detection, and other bio-devices
• Graphene transistors
• Integrated circuits, or conducting electrodes. In fact a graphene electrode will be transparent, with high electrical conductivity. Grapene might be used for touchscreens, especially suited for OLED displays.
• Ultracapacitors
• Spintronics-related products

As you can see, it's pretty exciting - many things can be done with Graphene. The main problem is that it's hard to manufacture a single sheet of Graphene. But several companies and research institutes are already working on new techniques to do just that.
