SUMMARY
The current density may exhibit complex patterns depending on the external bias, electrostatic environment, chip geometry, and magnetic_field. Giant nonlocality in magnetic_field While traditional studies of electronic transport tended to focus on low temperatures, more recent experimental work has been gradually shifting towards measurements at nearly room temperatures. At low temperatures and in strong magnetic_fields, graphene exhibits the quantum Hall effect (QHE) with well-defined plateaus in Hall resistivity corresponding to regions of the carrier density where ρx x=0. Given the exact particle-hole symmetry at neutrality, this system is "compensated" and hence . . .
