High‐Performance Visible to Near‐Infrared Broadband Bi 2 O 2 Se Nanoribbon Photodetectors
Owing to its suitable electronic bandgap, excellent air stability, and high carrier mobility at room temperature, low‐dimensional bismuth oxyselenide (Bi 2 O 2 Se) has become attractive in the context of visible–near‐infrared (VIS–NIR) detection. However, the high carrier concentration and bolometri...
