Twisted double ABC-stacked trilayer graphene with weak interlayer coupling

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.
