Impurity charge compensation in graphene by a polarized ferroelectric polymer and its effect on charge transport near the Dirac point

Charge transport near the Dirac point (DP) was investigated in graphene using ferroelectric (FE) gating in the temperature range of 300 < T < 350 K. We observed that the conductivity (σ) near the DP had a positive temperature gradient that switched to a negative temperature gradient with incre...
