Enhanced recombination rate, and thus electrical modulation , is achieved on a novel plasmonic platform that exploits the spontaneous formation of a V‐pit‐texture on the surface of an InGaN blue light‐emitting diode (LED). As a result of the geometry, sharpness, and high density of V‐pits, the decay rate can be increased 15‐fold even when the quantum well (QW) is separated more than 120 nm from the Ag coated V‐pits.
