  Abstract:
Bilayer graphene has recently attracted a great deal of attention because of its electrically tunable energy gaps and its unusual electronic structure. The aim of this chapter is electronic transport in bilayer graphene with the emphasis on fundamental physics and also conceptual issues. For this purpose, we begin with reviewing basic concepts in bilayer graphene describing a model Hamiltonian and opening the gap in the system. We then focus on the transport properties of bilayer graphene discussing the conductance in p-n junction, self-consistent Born approximation, RKKY interactions in biased bilayer graphene which are largely motivated by on-going experimental work on suspended bilayer graphene and on new-generation bilayer graphene samples on SiC. Besides, investigating the role of many-body e ects in these systems is crucial to understand upcoming experimental results. We therefore discuss about the collective modes in the symmetry and asymmetry charge density channels and the e ective mass as an essential quantities in quasiparticle theories. We then study in depth the charge compressibility in bilayer graphene.
