Landau Level Splittings, Phase Transitions, and Nonuniform Charge Distribution in Trilayer Graphene
Landau Level Splittings, Phase Transitions, and Nonuniform Charge Distribution in Trilayer Graphene
We report on magneto-transport studies of dual-gated, Bernal-stacked trilayer graphene (TLG) encapsulated in boron nitride crystals. We observe a quantum Hall effect staircase which indicates a complete lifting of the twelve-fold degeneracy of the zeroth Landau level. As a function of perpendicular electric field, our data exhibits a sequence of …
