First Principles Calculation Of Thermoelectric Parameters Of Monolayer- And Bilayer-Graphene And Heterostructures Of Graphene And H-Bn

Electrical conductivity and Seebeck coefficient were calculated using Boltzmann transport theory based on first-principles bandstructure calculations for the monolayer- and bilayer-graphene. We also present calculations of the thermoelectric parameters of Graphene/hBN/Graphene sandwiched heterostructures. These results will be discussed in the light of existing experimental data.
