Electrical conductivity reaches only half of the theoretical graphite limit in graphene assemblies, indicating significant performance gaps.
Integrated modeling reveals a percolation transition in graphene's basal plane near a sp2 fraction of 60%, influencing conductivity.
Experimental validation supports the framework's predictions on the impact of sheet size and defects on electrical performance.
Significantly higher anisotropy of electrical versus thermal conductivity suggests optimization strategies for material use.
