Electrical properties of graphene
3 August 2009The electrical properties of carbon nanoribbons has recently been studied and found that its current carrying capacity is much higher than copper. Researchers from Georgia Institute of Technology have reported that the narrow width graphene can have current carrying capacity as much as thousand times that the copper.
Researchers at Georgia Tech’s Nanotechnology Research Centre found that 16 nanometer wide graphene ribbon have current carrying capacity by a minimum of two orders of magnitude higher than copper and the excellent current carrying capacity of these is related to the resistivity. The measurements carried out by researchers for thermal conductivity and breakdown current density were published in 19th June edition of the Journal Applied Physics Letters.
Raghunath Murali, senior research engineer at Georgia Tech’s Nanotechnology Research Centre and his colleagues carried out a number of measurements including thermal conductivity on graphene of selected width range to use graphene as interconnects in place of copper. The current carrying capacity as measured by the research team was in the range of 10^8 to 10^9 amps per square centimeter. This is really perfect material to use in the chip, which will make the chip more reliable and resist electromigration up to a great extent.

Nanoribbons of graphene are an interesting new stage for nanoscience with implications for the modeling of picostructural material features. The gains from quantum physics understanding of the graphene topological details of atomic dimensions should progress exponentially as science defines more efficient, safer applications designed at the level of femtotechnical electron structure as well.
That reduction of scale must develop techniques to match the RQT (Relative Quantum Topological) context of chemical physics by combining the relativistic Lorenz-Einstein transform functions for time, mass, and energy with the quantized wavefunctions for wave frequency and wavelength.
RQT modeling of a semiconductor integrated circuit would define picoyoctometric 3D animated video imaging for photon gain events or other states and reactions like current flow. That application is apt, since the electron model developed by RQT series differential expansion of the Schrodinger equation of one atom shows all pymtechnical details of electron quantum shifts to accelerated states of wavectron material resonance. This model includes relativistic heat factors for electron topological thermic tints.
When the GT integral atomic wavefunction is applied to graphene nanoribbons they may be 3D video imaged for all of the atoms’ pymtechnical internal heat capacity energy waveparticles: positrons, workons, superworkons, thermons, electromagnetons, magnemedons. The RQT function system is introduced at http://www.symmecon.com, where mathematical point set images of the h-bar magnetic waveparticle of ~175 picoyoctometers are displayed.
