摘要

In this paper, bilayer pseudospin FET (BiSFET) is fabricated and tested for the condensate using Coulomb drag measurements in the double layer graphene system. The basic BiSFET structure can also be used as 2D-2D single particle tunnel FET, and the single particle h-h and e-e 2D-2D tunnel FETs, which is graphene's single-atom thickness could lead to more ideal interlayer tunneling characteristics provided the layers can be aligned. Single particle tunneling current calculations have been performed which show NDR characteristics, reminiscent of the BiSFET, albeit with higher operating powers.
