We have performed magneto-transport experiments in bilayer and trilayer graphene, at temperatures between 2 and 190 K and magnetic fields up to 22 T. Here we study the observation of the quantum Hall effect in bilayer and trilayer graphene. We have observed the quantum Hall plateaus at v = 4, 8, 12, 16, 20 in bilayer graphene and the quantum Hall plateaus v = +/- 6 and studied their temperature dependence. We have also studied the symmetry properties which are related with different contact configurations and describe the method used to study inhomogeneous samples

Abstract
We have performed magneto-transport experiments in bilayer and trilayer graphene, at temperatures between 2 and 190 K and magnetic fields up to 22 T. Here we study the observation of the quantum Hall effect in bilayer and trilayer graphene. We have observed the quantum Hall plateaus at v = 4, 8, 12, 16, 20 in bilayer graphene and the quantum Hall plateaus v = +/- 6 and studied their temperature dependence. We have also studied the symmetry properties which are related with different contact configurations and describe the method used to study inhomogeneous samplesFile in questo prodotto:
