To provide a more complex example of the various boundary conditions and geometries that HADOKEN can handle, Fig. depicts the self-consistent band-bending diagram and electron density for a core-multishell nanowire with a fixed Fermi level and more intricate doping density function. These input parameters correspond to a hexagonal nanowire with an n-type doping density of the form n D ( x, ỹ) = 5 exp [-0.1( x2 + ỹ2 )] cm -3 , a fixed Fermi level of -0.2 eV, an inner core/shell length of 20 nm/35 nm, outer core/shell length of 50 nm/65 nm. As shown in Figs. and, the self-consistent total electron density this coremultishell NW exhibits a much more complex total of twelve quasi-one-dimensional electron gases are visible, with the first six located at the inner quantum well's vertices and the other six at the outer quantum sheet-like distribution at each of the GaN/AlGaN interfaces of the outer quantum well.
