7 Jun 2006 | Journal: | Phys. Rev. B 73, 245403 (2006) | Subject: | Mesoscopic Systems and Quantum Hall Effect | Abstract: | The transport properties of a bilayer graphene are studied theoretically within a self-consistent Born approximation. The electronic spectrum is composed of $k$-linear dispersion in the low-energy region and $k$-square dispersion as in an ordinary two-dimensional metal at high energy, leading to a crossover between different behaviors in the conductivity on changing the Fermi energy or disorder strengths. We find that the conductivity approaches $2e^2/pi^2hbar$ per spin in the strong-disorder regime, independently of the short- or long-range disorder. | Source: | arXiv, cond-mat/0606166 | Services: | Forum | Review | PDF | Favorites |
