Trilayer Graphene

Trilayer Graphene is really interesting. It has some conduction bands like single layer (two almost linear) and some like bilayer, viz., four parabolic bands. The breaking of mirror reflection symmetry leaves just two bands in the vicinity of zero energy increasing minimum conductivity. One has to wonder about the puddling of excitons at concurrant one third filling of all three layers. Will the excitons form a Bose Einstein condensate when you apply comparable currents in opposite direction between the inner and outer layers assuming the Zeeman energy, temperature, density imbalance, layer spacing and applied magnetic field are reasonable? If so, it seems like this might be very useful in energy storage and making sensors. The more layers the flatter it gets!
