The z-dependent density of a stack averaged within a 2.5 Å thick sliding cuboid, centered at z and integrated over the lateral r = (x, y) coordinate across the entire lateral extent of the stack. The shaded regions show the 2.5 Å cuboid representing (blue) the top of c-Si, and (yellow) the bottom of the a-Si:H. The peak height in both regions shows the smooth transition of the Si density across the interface, similar to the desired structure of the transition zone passivating layer.
