ABSTRACT:
A single heterostructure light emitting device which provides high speed and high efficiency. The device includes adjacent n- and p- regions of a mixed-crystal III-V semiconductor such as GaAlAs. A lightly-doped wide bandgap injection layer is utilized to force recombination in the more heavily-doped adjacent region. The latter region also includes a graded bandgap which allows photon recycling for high efficiency.
