Researchers have realized optically and electrically
driven mid-infrared (MIR) light-emitting devices in a simple but
novel van der Waals (vdW) heterostructure constructed from
thin-film black phosphorus (BP) and transition-metal
dichalcogenides (TMDC). This work suggests that vdW heterostructure
is a promising platform for mid-infrared research and
applications.
