Most smartphone and computer users are bothered with the fact that
these electronic devices dissipate heat as part of its energy consumption// And
a new research will change the entire course of electronic history with a
graphene-based film used to cool devices// Several efficient ways are being
developed on how to effectively get rid of the excess heat which will help
prolong the lifespan of electronic components and circuits// A team of
researchers at the Chalmers University of Technology, Sweden successfully
developed a tool that will cool down electronics – reducing to half of its
total energy usage// Electronics has been highly linked to the increasing
consumption of energy; thus, it is directly related to the pollution that is
occurring worldwide// If the excess heat is efficiently removed, then there
would be considerable reduction in energy usage among electronic users// The
newly synthesized film is attached to component of electronics which are made
of silicon// Silicon is already known to have high thermal conductive capacity
that is four times greater than that of Copper// The same team led by Professor
Johan Liu of Chalmers University were successful in showing that graphene has a
cooling effect on silicon-based electronics// But things aren’t as easy as that
because they had to find a way to attach the thick layer of graphene on silicon
chips// Liu reported, **We have solved this problem by creating strong covalent
bonds between the graphene film and the surface, which is an electronic
component made of silicon//** He added, **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//** This kind of bonding made by the researchers results to
doubled thermal conductivity of graphene// Liu is proud to say that the
graphene-based film could be the future of electronics making **faster,
smaller, more energy efficient, sustainable high power electronics//**
