Better understanding of conduction in graphene brings terahertz closer processors




Scientists have discovered the Max Planck Institute how electrons in graphene behave as it rapidly electrical currents pass through the material. The find is a clue to build processors with terahertz clock speeds.

The experiments were performed by researchers from the Max Planck Institute performed by electric currents by guiding graphene with very short time intervals. The time between the streams is expressed on the picosecond scale, or one thousandth of a billionth of a second. Next, the researchers observed that the electrons in graphene starts to behave in such short intervals as if they are in a gas state. The discovery is published in the authoritative scientific journal Nature Communications.

According to the Max Planck Institute provide the currents for increased thermal activity of the electrons. This phenomenon causes the behavior of the electrons describe simple as applying thermodynamic laws. The increase in heat in the graphene is evenly distributed on the electrons, and this then has an effect on the resistance in the material, according to the scientists.

By better understanding how graphene behaves when the picosecond-scale electric currents through the hunting can be fabricated on possible applications here. For the hand is to develop processors with higher clock rates. According to the scientists, the discovery opens up opportunities for developing processors with clock speeds on the terahertz scale. When such technology can be applied in conventional desktop processors, however, remains unclear.
