Self-Assembled Moiré Superstructure of Ti₃C₂T_x MXene

The atomically reconstructed moiré superlattice and its impact on the microscopic electronic structure remains absent. In this investigation, we meticulously inspect and compare the self-assembled moiré superlattices of MXene. Employing a combination of experimental scanning tunneling microscopy/spectroscopy and ab initio simulations, we investigated three distinct self-assembled moiré patterns characterized by wavelengths approximately around 2.32 nm, 2.17 nm, and 1.12 nm. Our results illuminate a non-monotonic behavior in the moiré potential concerning moiré periods on the conductance band side. This research not only contributes to a detailed comprehension of MXene’s moiré phenomena but also establishes a fresh foundation for further exploration into unique correlated phases.
