A study of the luminescence properties of epitaxial GaP containing atomic N grown by molecular beam epitaxy using NH3 and PH3 as the column V sources was conducted. The 77 K photoluminescence spectra of the N‐doped epitaxial GaP showed a continuous redshift, from 5691 A (2.18 eV) to 6600 A (1.88 eV), resulted when the N concentration exceeded ∼5–7×1019 cm−3. This energy shift was found to be consistent with energy gap predictions using the dielectric theory of electronegativity for the GaP1−xNx…

Effects of nitrogen on the band structure of GaNxP1−x alloys

We report that the incorporation of N in GaNxP1−x alloys (x⩾0.43%) leads to a direct band-gap behavior of GaNP. For N concentration lower than 0.43%, a series of sharp emission lines from the various

Bowing parameter of the band-gap energy of GaNxAs1−x

We report a study of nitrogen incorporation in GaAs using a N rf plasma source. The N composition can be increased by lowering the growth temperature. X-ray diffraction shows no phase separation.
