▎ 摘　　要

ABC-stacked trilayer graphene's chiral band structure results in three (n = 0, 1, 2) Landau level orbitals with zero kinetic energy. This unique feature has important consequences on the interaction-driven states of the 12-fold degenerate (including spin and valley) N = 0 Landau level. In particular, at many filling factors nu(T) = +/- 5, +/- 4, +/- 2, +/- 1 a quantum phase transition from a quantum Hall liquid state to a triangular charge-density wave occurs as a function of the single particle-induced Landau level orbital splitting Delta(LL). Experimental signatures of this phase transition are also discussed.
