(Phys.org) —The mention of a two-dimensional material with excellent electrical and optical properties may first bring to mind graphene. However, this description also fits another class of materials called transition metal dichalcogenides (TMDs). Although TMDs in bulk form have been studied for decades—before graphene was even discovered—only recently they have been isolated to monolayers. With recent advances in nanomaterial characterization, scientists have recognized the potential of monolayer TMDs in applications such as LEDs, optical energy conversion, and other 2D optoelectronics technologies.
