  • The origin of 2.78 eV emission and yellow coloration in bulk AlN substrates
    Sedhain, A.; Du, L.; Edgar, J. H.; Lin, J. Y.; Jiang, H. X. (2009)
    The yellow color of bulk AlN crystals was found to be caused by the optical absorption of light with wavelengths shorter than that of yellow. This yellow impurity limits UV transparency and hence restricts the applications ...
  • Photoluminescence properties of AlN homoepilayers with different orientations
    Sedhain, A.; Nepal, N.; Nakarmi, M. L.; Al tahtamouni, T. M.; Lin, J. Y.; Jiang, H. X.; Gu, Z.; Edgar, J. H. (2008)
    AlN homoepilayers and heteroepilayers were grown on polar c-plane and nonpolar a-plane and m-plane orientations of AlN bulk and sapphire substrates by metal organic chemical vapor deposition. A systematic comparative ...
