Web1 okt. 2014 · A Kratos AXIS Ultra X-ray photoelectron spectroscopy (XPS) was used to study the chemical structure of the 50 nm thick films, using Al (1486.69 eV) X-ray source at 50° incidence angle. An argon ion gun (4 keV) was used to probe the depth of the samples. The etch rate was experimentally determined to be ∼2 nm/min. Web13 jun. 2014 · The energy gap of AlN in the zinc-blende structure is 6.1 eV, almost twice that of GaN (3.25 eV). Comparing GaN and AlN, the same sequence of states is seen for all the native defects. The positions of the states in the gap are also similar, with the general rule that they are lying somewhat deeper in the energy gap in AlN.
