## Description

- description: Moiré superlattice created by twist stacking has novel physical properties.
    These physical properties depend on the twist angle, hence investigation of the
    twist angle dependency is important for the deep understanding of physical phenomena
    in moiré superlattice. In this work, negative magnetoresistance owing to weak
    localization (WL) was investigated in twisted double bilayer graphene (TDBG) as
    a function of the twist angle. The ratio of the intervalley scattering time to
    the intravalley scattering time, estimated using the WL formula for bilayer graphene,
    tended to decrease as the twist angle increased. This feature is qualitatively
    explained by the enhancement of intervalley scattering due to the reduction of
    the intervalley distance in the moiré Brillouin zone (BZ) of the TDBG. This indicates
    that WL in the TDBG occurs for the moiré superlattice with the reconstructed BZ.
