| Abstract | Abstract
Single-layer (SL) transition-metal chalcogenides (TMCs) represent an important family of two-dimensional (2D) materials that have attracted intensive research attention recently. It has been established that many TMCs are polymorphic that can exist in different crystal structures and correspondingly exhibit diverse physical properties. Discovery of new structural phases of a crystal is of great scientific and practical importance. In this work, we report a new polymorph of SL-TMC, i.e. SL-Mo
