In a p-n junction, is it only the electrons that move from the n-type part to the p-type part in order to create a depletion region or is it the movement of both electrons and holes from the n-type and the p-type respectively? If it is so, then the whole idea of a depletion region seems flawed, considering how there is a net movement of electrons and holes both. Can someone explain?

  • $\begingroup$ Holes are absence of electrons. When one electron in a region move to the other, a hole is generated there. $\endgroup$ – walber97 May 18 '19 at 15:36
