Performance characteristics of strongly correlated bilayer graphene for post-CMOS logic devices

Abstract

Post-CMOS logic in bilayer graphene is very promising due to the possibility of observing room temperature collective states. We present calculations of graphene bilayers and the conditions necessary for excitonic superfluidity. At room temperature, the maximum current the condensate can support is increased over low temperature values and we can achieve negative differential resistances greater than 3 orders of magnitude between the condensate current and the non-interacting quasiparticle current which flows after exceeding the maximum current.
