Although O is an element of chalcogen group, the study of two-dimensional (2D) O-based Janus dichalcogenides/monochalcogenides, especially their 1T-phase, has not been given sufficient attention.
Two-dimensional (2D) materials with moderate bandgap and high carrier mobility are decent for the applications in the optoelectronics. In this work, we present a systematically investigation of the mechanical, electronic...
