Abstract

We utilized in situ transmission electron microscopy to observe phase transformation in CVD-grown MoS₂. Significantly, the reaction was performed under electron irradiation through appropriate control of the electron dose and exposure time. Moreover, we proposed a new route between the 2H and 1T phases that involved the higher energy states TS1/TS2.
