Dark Emitting Diode

Dark Emitting Diode a.k.a Light Canceling LED

DEDs consist of a small semiconductor chip with a P/N junction coupled to an embedded quantum vacuum cavity. When reverse-biased, the cavity absorbs photons proportionally to the current flow through the junction. For more information, see the article "Zener-enhanced Dark Emitting Diodes (ZeDEDs) deliver 10X more Dark per Watt" in this issue.
