  • Patent number: 11476383
    Abstract: A device that includes a metal(III)-polar III-nitride substrate having a first surface opposite a second surface, a tunnel junction formed on one of the first surface or a buffer layer disposed on the first surface, a p-type III-nitride layer formed directly on the tunnel junction, and a number of material layers; a first material layer formed on the p-type III-nitride layer, each subsequent layer disposed on a preceding layer, where one layer from the number of material layers is patterned into a structure, that one layer being a III-nitride layer. Methods for forming the device are also disclosed.
    Type: Grant

  • Publication number: 20220294189
    Abstract: Tunnel junctions (TJs) are used to invert a relative arrangement of the built-in polarization and current flow direction for metal (Ill)-polar grown Ill-nitride laser diodes (LDs). The resulting devices has subsequent TJ, p-type layers, active region and n-type layers. This arrangement ensures a band alignment which provides an injection efficiency of 100% without the need of close proximity of an electron blocking layer.
