Atomic-Scale In Situ Scanning Transmission Electron Microscopy of MoS₂ during Lithiation.

ABSTRACT: Atomic-scale in situ characterization techniques are necessary to clarify the dynamic local structural changes during intercalation reactions. High-resolution transmission electron microscopy (HRTEM) is at the forefront of this field. However, the image contrast in HRTEM is not always straightforward, necessitating the exploration of alternative imaging techniques. Here, using annular dark-field (ADF) scanning transmission electron microscopy (STEM), which is expected to provide a more directly interpretable image contrast, we report atomic-scale in situ observation of the MoS₂ lithiation process induced by electron irradiation. Using a single-crystalline specimen, dedicated specimen holder, and alternate low- and high-magnification image acquisition technique, a time series of
