I did a electronics apprentiship ~30-odd years ago & understood 50%
(enough for a pass mark). Then I had to teach it ~10 years ago...
What I discovered was that doping followed the laws of molecular
bonding. No surprises there.
The activity that produces the depletion layer commences with ionic
bonding (a dangling electron finds a greater attraction in a neighbour
atom's 'hole' orbit than its own orbit. This produces 2x ions). The
delpetion layer grows in width by this activity until the molecular
bonding forces That hole the donor atom orbits in place equal the ionic
bonding forces. Am I close? Did I lead those kids astray?

I learn in much the same way. Breaking complex behaviors down into
easily-understandable, intuitive component behaviors makes things much
easier for me to grasp.
