This chapter provides a tutorial style review on the physics of electronic transport through a graphene pn junction in the absence and presence of a magnetic field, including the case of a strain-induced pseudo-magnetic field. We review the basic transport theories for the graphene pn junction and complement this understandingwith numerical studies and key experimental findings. Novel devices, such as electron optics and strain-induced pseudo-magnetic devices, that exploit the physics of the graphene pn junction discussed in here, will be presented.
