Gate-tunable Magneto Transport in Consecutively-twisted Trilayer Graphene Moire of Moire Superlattices

ORAL

Abstract

Correlated insulating states and the transport signature of superconductivity have been reported in twisted trilayer graphene Moire of Moire superlattices [1]. Towards a further understanding of its underlying mechanism, we study the low-temperature magneto-transport in a dual-gated twisted trilayer graphene device and its dependence on an out-of-plane electric field. We comprehensively examine the role of each monolayer graphene layer in determining the rich electronic structure of the Moire of Moire superlattices.
