Carbon Nanotubes Graphene ppt
The "Wonder Material" revolutionized the world. Graphene. It's the Mother of all graphitic material. One single-atom thick Graphene is the world's strongest, thinnest, and most conductive.
One of the very first patents on graphene production was filed in October 2002 entitled, "Nano-scaled Graphene Plates“.
Two years later, in 2004 Andre Geim and Kostya Novoselov at the University of Manchester extracted single-atom-thick crystallites from bulk graphite. Geim and Novoselov received several awards for their pioneering research on graphene, notably the 2010 Nobel Prize in Physics.
Graphene Structure
- Graphene is a 2-dimensional network of carbon atoms.
- These carbon atoms are bound within the plane by solid bonds into a honeycomb array comprised of six-membered rings.
- By stacking these layers on top of each other, the well-known 3-dimensional graphite crystal is formed.
- It is a basic building block for graphitic materials of all other dimensionalities.
- It can be wrapped up into 0D fullerenes, rolled into 1D cabon nanotubes, or stacked into 3D graphite.
- Thus, graphene is nothing else than a single graphite layer.
Graphene Properties
- Graphene is chemically the most reactive form of carbon.
- graphene has high carrier mobility, as well as low noise
- It is a zero-overlap semimetal (with both holes and electrons as charge carriers) with very high electrical conductivity.
- High charge carrier mobility, for which values of 10,000 cm2/Vs, in some cases even 200,000 cm2/Vs were reported.
- Graphene, despite it is only 1 atom thick, is still visible to the naked eye.
- Due to its unique electronic properties, it absorbs a high 2.3% of the light that passes through it.
