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.

Graphene Applications

  • Biomedical- reading the sequence of chemical bases in a DNA strand 
  • Integrated circuits- High-Performance Processor, Terahertz-speed transistor
  • Optical Electronics-touchscreens, liquid crystal displays, organic photovoltaic cells, and OLED
  • Filters-Desalination, Ethanol distillation
  • Energy Storage Devices: Supercapacitors
