From: Improved p-type conductivity in Al-rich AlGaN using multidimensional Mg-doped superlattices
The isosurface of the valence states at the top of valance bands for Mg-doped 3D (a) and conventional (b) GaN/AlN SLs with k vector restricted to [0001]. (c) Decomposed DOS of px, py, and pz of Mg and bonded N atoms in 3D SL and conventional SL. The N bonded with Mg lying in the ab plane and out of the plane is respectively denoted as Nin and Nout in the inset.
