  • Publication number: 20240021753
    Abstract: A light-emitting diode (LED) device can include a mesa with a sidewall encompassing a first semiconductor layer, a second semiconductor layer, and an active region between the first semiconductor layer and the second semiconductor layer. The first semiconductor layer and the second semiconductor layer are oppositely doped. The active region includes a quantum well. The LED device can further include at least one epitaxial layer grown over the sidewall of the mesa. The at least one epitaxial layer comprises a semiconductor material having a wider bandgap than a semiconductor material of the quantum well and is configured to induce compressive or tensile strain in the quantum well. The compressive or tensile strain causes a bandgap of a peripheral portion of the quantum well to differ from a bandgap of a central portion of the quantum well, thereby tuning an emission profile (e.g., wavelength and/or intensity) of the LED device.

  • 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.
