Graphene Transistors to Create Self-Cooling Energy Efficient Electronics


Scientists are on the threshold of achieving an energy savingbreakthrough through the use of Graphene, which, in effect, is a thicksheet of carbon atoms with wonderful electrical properties. Moreover,these super capacitors with faster charging abilities and longer powerretention capacities can also be widely used as a replacement for NiHbatteries for hybrid autos.

Presently, scientists are trying to replace the silicon chips of the computers with Graphene super capacitors that will draw less energy and produce better cooling effects. Researchers at University of Illinoishave already established the “nanocooling effects of Graphenetransistors that help in reducing their temperatures”.

The high speed small sized computer chips with self coolingproperties could play a major role in saving significant amounts ofenergy. At present, computers are provided with fans or a steady waterflow to cool the heat dissipated by the transistors that drawconsiderable amount of energy. Moreover, the 1 atom thick Graphenecarbon sheets will enable the computer to operate at a higher speed than the silicon chips.

Researches have proved that “imperfections” in Graphene sheets haveenhanced their performance going against the norms of perfection anduniformity. After several attempts, a team of scientists have succeededin producing Graphene sheets with required degree of imperfections thatshowed better performance in integrated circuit.

The extremely tiny size of the Graphene transistors is the mainhurdle for the scientists to go for a mass application. An atomic forcemicroscope tip was required to probe the temperature measurements of aGraphene transistor on nanometer scale. As the scientists are gainingmore insight into the energy saving capabilities of Graphene, it will be a matter of few years for a huge turnaround in energy saving throughthese self cooling nanotransistors.
