▎ 摘 要
We investigate electronic band structure and transport properties in bilayer graphene superlattices of Thue-Morse sequence. It is interesting to find that the zero-(k) over bar gap center is sensitive to interlayer coupling t', and the centers of all gaps shift versus t' at a linear way. Extra Dirac points may emerge at k(y) not equal 0, and when the extra Dirac points are generated in pairs, the electronic conductance obeys a diffusive law, and the Fano factor tends to be 1/3 as the order of Thue-Morse sequence increases. Our results provide a flexible and effective way to control the transport properties in graphene. (C) 2013 AIP Publishing LLC.
