I got a quiery concerning the polarity of Electrons and Ions. I am most certain that the Electron is Negative (cathode) and the Ion is positive UUD (Anode).

The article however states : If we consider a p-type semiconductor (with the density of acceptors, p the density of holes; p = NA in neutral bulk), a positive voltage,, from gate to body (see figure) creates a depletion layer by forcing the positively charged holes away from the gate-insulator/semiconductor interface

...leaving exposed a carrier-free region of immobile, negatively charged acceptor ions (see doping (semiconductor))

Question : Negative charged Ions ? That makes no sense at all. The Ion is positive and stabile. That implies the Holes does not move. The negative Electrons move. In my understanding. Like a golfball (electron) putting into a (ion) hole.
