In article number 1700268, Qiaoliang Bao and co‐workers, report a highly efficient flexible MoTe2/graphene heterostructure photodetector that is fabricated for near‐infrared light detection. The devices exhibit a high responsivity that is nearly one thousand times better than a commercial photodiode at 1064 nm.
2D transition metal dichalcogenides (TMDCs) have attracted considerable attention due to their impressively high performance in optoelectronic devices. However, efficient infrared (IR) photodetection has been significantly hampered because the absorption wavelength range of most TMDCs lies in the visible spectrum. In this regard, semiconducting 2D MoTe2 can be an alternative choice owing to its smaller...
