Twisted double ABC-stacked trilayer graphene with weak interlayer coupling

verfasst von: Sung Ju Hong, Donglei Wang, Dirk Wulferding, Peter Lemmens, Rolf J. Haug
Abstract: Magnetotransport properties of single- and double-rhombohedral trilayer graphene (TLG) are studied. Double TLG is obtained by folding single TLG, yielding a twist angle of 4°. Raman spectroscopic measurements confirm ABC stacking order and the presence of interlayer coupling. The Landau fan diagram exhibits independently superimposed features of each constituent TLG, indicating weak interlayer coupling. As a result, we show that the current framework for twisted systems can be extended to TLG.
