TLDR
This work reviews the progress that has been made with carbon nanotubes and, more recently, graphene layers and nanoribbons and suggests that it could be possible to make both electronic and optoelectronic devices from the same material.Abstract:
The semiconductor industry has been able to improve the performance of electronic systems for more than four decades by making ever-smaller devices. However, this approach will soon encounter both scientific and technical limits, which is why the industry is exploring a number of alternative device technologies. Here we review the progress that has been made with carbon nanotubes and, more recently, graphene layers and nanoribbons. Field-effect transistors based on semiconductor nanotubes and graphene nanoribbons have already been demonstrated, and metallic nanotubes could be used as high-performance interconnects. Moreover, owing to the excellent optical properties of nanotubes it could be possible to make both electronic and optoelectronic devices from the same material.read more

Plasmon mass and Drude weight in strongly spin-orbit-coupled two-dimensional electron gases
Amit Agarwal,Stefano Chesi,Tomas Jungwirth,Jairo Sinova,Jairo Sinova,Giovanni Vignale,Giovanni Vignale,Marco Polini,Marco Polini +8 more
TL;DR: In this paper, the long-wavelength plasmon dispersion and the Drude weight of archetypical spin-orbit-coupled 2DEGs were studied and it was shown that these measurable quantities are sensitive to electron-electron interactions due to broken Galilean invariance.

The rise of graphene
TL;DR: Owing to its unusual electronic spectrum, graphene has led to the emergence of a new paradigm of 'relativistic' condensed-matter physics, where quantum relativistic phenomena can now be mimicked and tested in table-top experiments.
