Se‐doped black phosphorus (BP) crystal, in centimeter scale, is synthesized by a scalable gas‐phase growth method under mild conditions. The Se‐doped BP exhibits high quality with excellent electrical properties. The Se dope induces over 20‐fold enhancement of responsivity ( R ) for BP‐based 2D photodetectors, resulting in a high R and external quantum efficiency of 15.33 A W −1 and 2993%, respectively.
