Experimental … Witryna9 sie 2024 · As the polarization varies when the temperature changes, both the impurity charge concentration ( ni) and the carrier charge density ( n) vary, so they both are temperature-dependent. We suggest that these dependencies may explain the temperature dependence of the graphene conductivity observed in our experiments.
