  • Patent number: 11362237
    Abstract: A micro-light emitting diode (micro-LED) includes a current aperture to confine the current in a localized region such that the carrier recombination mostly occurs in the localized region to emit photons, thereby reducing the surface recombination and improving the quantum efficiency. The current confinement and localization are achieved using a localized breakthrough of a barrier layer by a localized contact, lightly p-doped active layers to suppress lateral transport of the carriers to the surface region, selective ion implantation, etching, or oxidation of a semiconductor layer, or any combination thereof.

  • Patent number: 10680135
    Abstract: The invention relates to an optoelectronic component (100) comprising a semiconductor layer sequence (1) having an active layer (10), wherein the active layer (10) is designed to produce or absorb electromagnetic radiation in intended operation. Furthermore, the component (100) comprises a first contact structure (11) and a second structure (12), by means of which the semiconductor layer sequence (1) can be electrically contacted in intended operation. In operation, a voltage is applied to the contact structures (11, 12), wherein an operation-related voltage difference ?Ubet between the contact structures (11, 12) arises. When the voltage difference is increased, a first arc-over occurs in or on the component (100) between the two contact structures (11, 12). A spark gap (3) between the contact structures (11, 12), which arises in the event of the first arc-over, passes predominantly through a surrounding medium in the form of gas or vacuum and/or through a potting.
