Electronic spectral properties of incommensurate twisted trilayer\n graphene

Le résumé fourni par la source

Multilayered van der Waals structures often lack periodicity, which\ndifficults their modeling. Building on previous work for bilayers, we develop a\ntight-binding based, momentum space formalism capable of describing\nincommensurate multilayered van der Waals structures for arbitrary lattice\nmismatch and/or misalignment between different layers. We demonstrate how the\ndeveloped formalism can be used to model angle-resolved photoemission\nspectroscopy measurements, and scanning tunnelling spectroscopy which can probe\nthe local and total density of states. The general method is then applied to\nincommensurate twisted trilayer graphene structures. It is found that the\ncoupling between the three layers can significantly affect the low energy\nspectral properties, which cannot be simply attributed to the pairwise\nhybridization between the layers.\n
