Two-dimensional (2D) vertical heterostructures (HSs), which are constructed via vertically stacking two or more 2D transition metal dichalcogenide (TMDC) materials, had been intensively studied during the past several years. However,...
Valley pseudospin of 2D transition-metal dichalcogenides is promising for information technologies, but its robust manipulation is challenging. This minireview highlights recent progress on using nanophotonic strategies to address this challenge.
