Abstract
An optoelectronic device having a highly conductive carrier tunneling current aperture. The device includes a centrally positioned current aperture formed from a quantum layer made of a III-IV-V semiconductor compound, which is doped with a first doping type. The current aperture is laterally confined by an oxide of the III-IV-V semiconductor compound. Adjacent layers are also formed of a semiconductor material that is doped with the first doping type.
