Heat to Electricity Conversion by a Graphene Stripe with Heavy Chiral Fermions

Abstract
A conversion of thermal energy into electricity is considered in the electrically polarized graphene stripes with zigzag edges where the heavy chiral fermion (HCF) states are formed. The stripes are characterized by a high electric conductance Ge and by a significant Seebeck coefficient S. The electric current in the stripes is induced due to a non-equilibrium thermal injection of "hot" electrons. This thermoelectric generation process might be utilized for building of thermoelectric generators with an exceptionally high figure of merit ZδT \simeq 100 >> 1 and with an appreciable electric power densities \sim 1 MW/cm2.
