Abstract

Mid-IR light emitting diodes (LEDs) based on type-II quantum dot (QD) active regions grown with monolithically integrated semiconductor metal layers are provided. These LEDs comprise layers of type-II semiconductor (e.g., InGaSb) quantum dots integrated into a pn junction diode (e.g., InAs) grown above a highly doped backplane, such as an n++ InAs backplane, all in the same epitaxial growth. Aspects described herein minimize non-radiate recombination times and significantly increase radiative recombination rates by controlling the emission of the emitting QDs in the near field of an optical metal.
