A publication made by Maria Temming in the science news website revealed a new property found in graphene which adds to its numerous advantageous properties.

Graphene as a material belongs to the allotropes of carbon element obtained from graphite, has been a material that holds much hope for researchers and scientists. First was its prediction in the making of superior, light-weight, and short-time power charging and long-time power discharging battery. The battery from graphene was predicted to have the potential of changing the electrically powered machines’ technology. It can be charged within a short time and spend durable time in its discharging period.

Maria’s publication revealed that a single layer of carbon atoms can boost signals from gigahertz to terahertz frequencies.  Such transformation of frequency can shuttle up to 1000 times as much information per second.

The experiment conducted with graphene showed that Graphene-based devices could handle electromagnetic waves in the terahertz range. Meanwhile, electromagnetic waves in the terahertz range are obviously difficult to create and conventionally silicon-based electronics have trouble in handling such high-frequency signals. That demonstrates the superiority of graphene in handling high-frequencies.

The report said that this new property found in graphene means it could make future electronics work much faster than today’s devices.

The test conducted by a Physicist Dmitry Turchinovich of the University of Duisburg-Essen in Germany and colleagues made this new feature of graphene to be found. A report said, “The group tested graphene’s terahertz-producing prowess by injecting a sheet of thin atom-thick material with 300-gigahertz radiation. As the electromagnetic waves hit the graphene, electrons in the material rapidly heated and cooled off, releasing electromagnetic waves with frequencies up to seven times as high as the incoming radiation.” The 2-D material used in the test can be viewed as a super-material that conducts electricity with no resistance.Light, Bokeh, Shining, Yellow, Red

Another physicist not involved in the research exclaimed that the graphene’s ability means it was able to convert more than a thousandth, a ten-thousandth and a hundred-thousandth of the original 300-gigahertz signal into waves at 0.9, 1.5 and 2.1 terahertz respectively. Though it may seem small but such is remarkable and high for a lone layer of atoms.

“This new property found in Graphene’s 2-D material means it could be used for extremely high-speed Nanodevices and very advanced computers with high processing rates.”

With such material, it will be possible to have Graphene-based computer components that can deal in terahertz.
