Raman characterization of ABA- and ABC-stacked trilayer graphene.
Bernal (ABA stacking order) and rhombohedral (ABC) trilayer graphene (3LG) are characterized by Raman spectroscopy. From a systematic experimental and theoretical analysis of the Raman modes in both of these 3LGs, we show that the G band, G' (2D) band, and the intermediate-frequency combination modes of 3LGs are sensitive to the stacking order of 3LG. The phonon wavevector q, that gives the dou...
متن کاملLandau level spectrum of ABA- and ABC-stacked trilayer graphene
We study the Landau level spectrum of ABAand ABC-stacked trilayer graphene. We derive analytic lowenergy expressions for the spectrum, the validity of which is confirmed by comparison to a π -band tight-binding calculation of the density of states on the honeycomb lattice. We further study the effect of a perpendicular electric field on the spectrum, where a zero-energy plateau appears for ABC ...
متن کاملBroken symmetry quantum Hall states in dual-gated ABA trilayer graphene.
ABA-stacked trilayer graphene is a unique 2D electron system with mirror reflection symmetry and unconventional quantum Hall effect. We present low-temperature transport measurements on dual-gated suspended trilayer graphene in the quantum Hall (QH) regime. We observe QH plateaus at filling factors ν = -8, -2, 2, 6, and 10, which is in agreement with the full-parameter tight binding calculation...

متن کاملTransport spectroscopy of symmetry-broken insulating states in bilayer graphene.
Bilayer graphene is an attractive platform for studying new two-dimensional electron physics, because its flat energy bands are sensitive to out-of-plane electric fields and these bands magnify electron-electron interaction effects. Theory predicts a variety of interesting broken symmetry states when the electron density is at the carrier neutrality point, and some of these states are character...
