Abstract
We report markedly different transport properties of ABA- and ABC-stacked trilayer graphenes. Our experiments in double-gated trilayer devices provide evidence that a perpendicular electric field opens an energy gap in the ABC trilayer, while it causes the increase of a band overlap in the ABA trilayer. In a perpendicular magnetic field, the ABA trilayer develops quantum Hall plateaus at filling factors of ν= 2, 4, 6... with a step of Δν= 2, whereas the inversion symmetric ABC trilayer exhibits plateaus at ν= 6 and 10 with 4-fold spin and valley degeneracy.
