重手征费米子石墨烯带的热电转换
Heat to Electricity Conversion by a Graphene Stripe with Heavy Chiral Fermions
摘要：
在具有锯齿形边缘的电极化石墨烯条带中考虑热能到电的转换，其中形成重手征费米子（HCF）态。条纹的特征在于高电导率Ge和显著的塞贝克系数S。条纹中的电流是由于“热”电子的非平衡热注入而引起的。该热电发电过程可用于构建具有特别高的品质因数ZδT \simeq 100 >> 1和具有可观的电功率密度\sim 1 MW/cm 2的热电发电机。
英文摘要：
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.
