    摘要: Nitride semiconductor films, such as for use in solid state light emitting devices and electronic devices, are fabricated in an environment of relatively high nitrogen potential such that nitrogen vacancies in the growing film are reduced. A reactor design, and method for its use, provide high nitrogen precursor partial pressure, precracking of the precursor using a catalytic metal surface, prepyrolyzing the precursor, using catalytically-cracked molecular nitrogen as a nitrogen precursor, and/or exposing the surface to an ambient which is extremely rich in active nitrogen species. Improved efficiency for light emitting devices, particularly in the blue and green wavelengths and improve transport properties in nitride electronic devices, i.e., improved performance from nitride-based devices such as InGaAlN laser diodes, transistors, and light emitting diodes is thereby provided.

    摘要: A semiconductor laser diode with a high indium content is provided with a lattice matched cladding layer or layers. One or both of the cladding layers may comprise bulk aluminum gallium indium nitride in the ratio of AlxGa1-x-yInyN and/or a short period superlattice structures of, for example, a plurality of alternating layer pairs of aluminum gallium indium nitride in the ratio of AlxGa1-x-yInyN and gallium indium nitride in the ratio of GasIn1-sN, providing a multi-quantum barrier (MQB) effect. Lattice matching of the cladding layer(s) and active layer reduce or eliminate strain, and the materials chosen for the cladding layers optimizes optical and carrier confinement. Alternatively, the lattice parameters may be selected to provide strain balanced MQBs, e.g., where the barrier layers are tensile-strained and the well layers compressed.
