History Of Research On Graphene
- Aug 22, 2016 -

Graphene is actually exist in nature, is difficult to split a single-layer structure. Graphene layers stack up graphite, graphite contains approximately 3 million thick 1 mm sheets of Graphene. Pencil on paper, gently across, leave no trace, can be for a few or even just one layer on top of Graphene.

Graphene is in a lab in 2004, at that time, the United Kingdom two scientists from the University of Manchester's Andre geim and kesiteya·nuowo consumer Rove find that they can use a very simple method to get more and more thin sheet of graphite. They stripped from highly oriented pyrolytic graphite graphite pieces, then stuck on both sides of the sheet on a special tape, tear tape, graphite can be divided into two parts. Do this constantly, so thin and thinner, finally, they got only one layer sheet of carbon atoms, that's Graphene. After that, the new way to produce Graphene emerge, after 5 years of development, it was found that industrial production of Graphene into areas not too far away. Therefore, over the next three years, andelie·gaimu and kangsitanding·nuowoxiaoluofu in single-layer and double-layer Graphene number system found in the entire Hall effect and quantum Hall effect under ambient conditions, they also won the 2010 Nobel Prize in physics.

Before the discovery of Graphene, most physicists believe that thermodynamic fluctuations do not allow any two-dimensional Crystal at finite temperatures. Therefore, it found immediate shock of condensed matter physics academia. Theory and experiment are considered perfect two-dimensional structure cannot be stable in non-absolute zero exists, but single-layer Graphene in the experiment were prepared.
