We have performed magneto-transport experiments in trilayer graphene, at temperatures between 2 and 190 K and magnetic fields up to 22 T. Here we report the integer quantum Hall effect in trilayer graphene, showing the quantum Hall plateau at ν=6 and studying its temperature dependence. The symmetry properties of the resistance in the quantum Hall regime and at low magnetic fields are also investigated. The measurements obey the reciprocity relation, and reveal new symmetries that relate the resistances measured with different contact configurations.

Abstract

We have performed magneto-transport experiments in trilayer graphene, at temperatures between 2 and 190 K and magnetic fields up to 22 T. Here we report the integer quantum Hall effect in trilayer graphene, showing the quantum Hall plateau at ν=6 and studying its temperature dependence. The symmetry properties of the resistance in the quantum Hall regime and at low magnetic fields are also investigated. The measurements obey the reciprocity relation, and reveal new symmetries that relate the resistances measured with different contact configurations.

Physica E (Low-dimensional systems and nanostructures) contains papers and invited review articles on the fundamental and applied aspects of physics in low-dimensional systems, including semiconductor heterostructures, mesoscopic systems, quantum wells and superlattices, two-dimensional electron systems, and quantum wires and dots. Both theoretical and experimental contributions are invited. Topics suitable for publication in this journal include spin related phenomena, optical and transport properties, many-body effects, integer and fractional quantum Hall effects, single electron effects and devices, and other novel phenomena.
