ABSTRACT
For more than 30 years, there has been a sustained academic interest and technical development effort directed at layered metal chalcogenides (LMCs) and their intercalation compounds. This in part is. due to the intriguing structural and physical properties of these two-dimensional (2D) inorganic materials [1]. In the general case, these structures consist of infinite metal chalcogenide layers; within each layer the atoms are bound by strong covalent interactions, but the layers themselves interact only by weaker van der Waals forces [2], For the most part, the metals involved are transition metals, although SnS2 is a well-known example of a main-group LMC.
