"GADGET'S USING GRAPHENE FILM"

Researchers at Chalmers University of Technology – Sweden, have developed a method for efficiently cooling electronics using graphene-based film. Almost half of the total energy used in running a computer goes in cooling it down. That is going to change now.

Getting rid of excess heat in efficient ways is imperative to prolonging electronic lifespan, and would also lead to a considerable reduction in energy usage, experts said. The film will be attached to the electronic components which is made up of Silicon and has thermal conductivity capacity which is four times than the copper.

Professor Johan Liu from Chalmers University had shown that the graphene have a cooling effect on Silicon-based electronics, but the challenge was to stick a thick layer of graphene to silicon chips.

According to the Prof Johan Liu, the problem can be solved by creating strong covalent bonds between the graphene film and the surface, which is an electronic component made of silicon. The functionalisation using this kind of bonding doubles the thermal conductivity of the graphene.

The Prof Liu states that “ Increased thermal capacity could lead to several new applications for graphene. One example is the integration of graphene-based film into microelectronic devices and systems, such as highly efficient Light Emitting Diode, lasers and radio frequency components for cooling purposes. He also said that Graphene-based film could also pave the way for faster, smaller, more energy efficient, sustainable high power electronics.
