Transfer current in p-type graphene/MoS2 heterostructures

Transfer characteristics of p-doped graphene/monolayer-MoS 2 heterostructure at 300 K are measured experimentally and analyzed based on a model calculation. In the model, we first discretize Poisson equation into multiple zones. each zone charge density is assumed constant can be transformed linear to determine chemical potential self-consistently. To calculate electrical conductivity, solve Boltzmann transport in relaxation-time approximation using inelastic acoustic phonon scattering by solving Dirac equation. The relationship between voltage (the which Fermi level located point) energy (i.e. initial 0 K) derived. These calculations performed without with optical pumping results obtained agree well experimental data. • Modeling transfer current graphene/MoS heterostructures. A multi-zone used potentials.
