In the contemporary times where technology is playing the real game, almost everybody uses a computer. All of them who do use want their respective computer to be swift in action. Obviously, who would not wish for a computer that takes more than five minutes to process the inputs. The speed of a computer depends on how quick electrons transmit the information between the processor and the memory. A team of researchers at MIT have discovered a way to fasten up the process using graphene sheet.
A team researchers from MIT have in fact found a solution to the problem that arises where photons have to be created back into electrons when a light is being used.
Earlier too running computers using lights was possible. However, the silicon chips used in the computers required the photons to be converted back into electrons. Mainly to enable processing. This would, in fact, defeat the process. As such a system would use more energy than usual. And further, slow down the process.
The recent discovery by the team from MIT involves the creation of a sort of shock wave of light. In theory, it is similar to the sonic boom shockwave, achieved when an aeroplane reaches or exceeds the speed of sound.
The researchers found out that they could use a sheet of graphene to produce an optical boom. Which is an intense, focused beam of light. It was observed that, when a light comes in contact with graphene, it slows down drastically. This slowed-down speed reaches almost the same speed as that of the electrons.
Graphene allows the passage of electrons up to 1/300 the speed of light in vacuum. Getting electrons and photons to almost the same speed could result in breaking the light barrier, and this could make operating speeds up to a million times faster.
Nevertheless, the production of the graphene sheet is expensive. Hence, there are studies going on to produce it at a cheaper rate.
