In Situ Formation of Ripplocations in Hybrid Organic-Inorganic MXenes.

ABSTRACT: Inorganic-organic hybrid MXenes (h-MXenes) are a family of 2D transition metal carbides and nitrides functionalized with alkylimido and alkylamido surface groups. Using cryogenic and room temperature scanning transmission electron microscopy (STEM) and electron energy-loss spectroscopy (EELS), it is shown that ripplocations, a form of a fundamental defect in 2D and layered structures, are abundant in this family of materials. Furthermore, detailed studies of electron probe sample interactions, focusing on structural deformations caused by the electron beam are presented. The findings indicate that at cryogenic temperatures (≈100 K) and below a specific dose threshold, the structure of h-MXenes remains largely intact. However, exceeding this threshold leads to electron beam-induced deformat
