Towards correlated electron states in trilayer-graphene Moiré band

ORAL

Abstract

The recent discovery of Moiré superconductivity in twisted-bilayer graphene (tBLG) and twisted-double bilayer-graphene (tDBG) systems [1][2][3] has generated a great amount of interest in the condensed matter community. Beyond this model system, this work focuses on studying a new Moiré platform based on the twisted trilayer-graphene. Preliminary magneto-transport measurements will be presented. Characterization of interlayer screening, band evolution with displacement field and Moiré periodicity will also be discussed.
