DO YOU KNOW ANY GRAPHENE PROPERTY?

One graphene property is that it is a perfect thermal conductor. Its thermal conductivity was recently measured at room temperature and is much higher than the value observed in all the structures of carbon nanotubes of carbon, graphite and diamond.

The ballistics of the thermal conductance graphene is isotropic, that is to say, equally in all directions. In a similar manner to the other physical properties of this material, its two-dimensional structures are particularly special.

The study of the thermal conductivity of this graphene property can have important implications in electronic devices based on graphene. As devices continue to shrink and increases the density of the circuit, high thermal conductivity, which is essential for the dissipation of heat efficient to keep fresh electronics, plays an increasing role in the reliability of the device.

Second graphene property is one of the thinnest material ever made, is still visible to the eye. Due to its unique electronic properties, absorbs a 2.3 % of the light that passes through it, which make it visible enough.

A third graphene property is that the graphene is similar to the surface of graphite, graphene can adsorb and desorb different atoms and molecules. Weakly attached adsorbates often act as donors or acceptors and lead to changes in the carrier concentration, so graphene remains highly conductive.

A fourth graphene property is that is flexible but hard at the same time. graphene is harder than diamond and steel. Although the graphene is so strong, it is also very elastic. The graphene can stretch up to 20% of its original length. It is expected that this graphene property you will find applications in a new generation of strong and flexible screens for mobiles.

Fifth graphene property is graphene is a great conductor. One of the hottest areas of graphene research focuses on the intrinsic electronic properties; how electrons flow through a sheet – only one atom thick – while under the influence of various external forces.

Why is this graphene property so interesting?

In the first place, the graphene is great conductor; electrons are able to flow easily through graphene than through the copper. The electrons travel through the graphene sheet, as fast as just one hundredth that of the speed of light.

Secondly, the electrons in graphene behave manner makes it very useful to explore some fundamental physical properties. Graphene’s near perfect crystal lattice mean it is a very clean system in which to experiment. By restricting the electrons to only two dimensions.
