- W293466475 abstract "Yellow luminescence (YL) has been studied in GaN:Mg doped with Mg concentrations ranging from 10{sup 19} to 10{sup 21} cm{sup {minus}3} by spectral CL (T = 5K) and TEM and explained by suggesting that a different mechanism could be responsible for the YL in p-type GaN with respect to that acting in n-type GaN. Transitions at 2.2, 2.8, 3.27, 3.21, and 3.44 eV were found. In addition to the wurtzite phase, TEM showed a different amount of the cubic phase in the samples. Nano tubes with a density of 3x10{sup 9} cm{sup {minus}2} were also observed by approaching the layer/substrate interface. Besides this, coherent inclusions were found with a diameter in the nm range and a volume fraction of about 1%. The 2.2 eV yellow band, not present in low doped samples, increased by increasing the Mg concentration. It was ascribed to a transition between a deep donor level at 0.8--1.1 eV below the CB edge due to N{sub Ga} and the shallow acceptor due to Mg{sub Ga}. This assumption was checked by studying the role of C in Mg compensation. CL spectra from a sample with high C content showed transitions between a C-related 200 meV shallow donor andmore » a deep donor level at about 0.9--1.1 eV below the CB due to a N{sub Ga}-V{sub N} complex. In their hypothesis this should induce a decrease of the integrated intensity in both the 2.2 and 2.8 eV bands, as actually shown by CL investigations.« less" @default.
