Few years we have been hearing about investigations into the use of graphene as a material for the creation of chips, processors and all kinds of electronic circuits. Until now it was known that this particular compound, consisting of a monatomic mesh of carbon atoms, is able to withstand amazing transfer speeds electrical impulses, making it the ideal replacement for silicon.
If the possibility of a graphene chip 1000Ghz frequency range is no longer attractive in itself, now science has discovered a second quality no less fascinating. Scientists at the University of Illinois have found that graphene is not only hot, but has the ability to 'self cooling'. One of the biggest problems of graphene is that its structure is within the field of nanotechnology.
Mononuclear thickness makes it particularly difficult to manipulate and measure. For the first time, a team of researchers led by physicist and engineer William King Eric Pop systems have measured the temperature of a grid of graphene using an atomic force microscope and a temperature sensor suitably adapted.
The results of these measurements have been unexpected. Graphene seems to lose heat more rapidly than it accumulates, which means that the material not only stays cold for a lot of electricity that is applied but the loss of heat could be harnessed to generate more electricity. According to Professor King's words: 'In the silicon and the majority of known materials, electric heating is much greater than the ability to dissipate that heat.
However, we found that there are areas where graphene transistors in which the thermoelectric cooling is superior to heat buildup, which would, in theory, design self-cooling devices without external assistance. This is the first time you see this quality in graphene devices. " The discovery opens the door to a whole new world of possibilities when designing high-density chips ultrafast, above, not hot.
Until now, graphene was extremely complicated and expensive to create because they had to remove the graphite nanosheets from common (the material from which the mines are made of pencils.) However, the technology of extraction of this material has come a long way and already have much cheaper costs.
It is too early to talk about when will the graphene laboratories, but it appears that this curious material could usher in a new technological era. Track | DailyTech More | University of Illinois
