Highly tunable spin-dependent electron transport through carbon atomic chains connecting two zigzag graphene nanoribbons
Highly tunable spin-dependent electron transport carbon atomic chains zigzag graphene nanoribbons
2012/2/27
Motivated by recent experiments of successfully carving out stable carbon atomic chains from graphene [Meyer et al. Nature (London) 454, 319 (2008); Jin et al. Phys. Rev. Lett. 102, 205501 (2009)] we ...
Effect of charged impurity correlation on transport in monolayer and bilayer graphene
charged impurity correlation transport monolayer bilayer graphene
2012/2/27
We study both monolayer and bilayer graphene transport properties taking into account the presence of correlations in the spatial distribution of charged impurities. In particular we find that the exp...
Manipulating infrared photons using plasmons in transparent graphene superlattices
Manipulating infrared photons plasmons transparent graphene superlattices
2012/2/27
Superlattices are artificial periodic nanostructures which can control the flow of electrons. Their operation typically relies on the periodic modulation of the electric potential in the direction of ...
