I feel Heat conduction in the subject should be considered.

I am in agreement with Dr DSP. A description is really needed for an understanding of the process.

So- how do you get vacancies into the lattice? Seems like that part of the process might be difficult. Would be nice to have a simple description...

Great story! Graphene is emerging as the universal alternative for the conductor, insulator, semiconductor and now magnetic material. Apart from being lighter, electronic gadgets using graphics are going to be faster (because of high electron mobility), more energy-efficient and smaller.

Graphene could serve as the conductor, insulator, semiconductor and now the magnetic material in future electronics. Silicon keeps on going by innovating, but the fact that carbon can substitute for metals as interconnects gives it a little cited advantage. Namely, that if all the copper conductors in a mobile device were made from graphene, then the device would be less than half the weight it is today. If everything in future handheld electronics was crafted from carbon films, they could become almost as light as styrofoam.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
