Electrons on the p-side near the edge of dep reg, due to drift, move across the dep region into the n-reg. They don't oscillate back and forth in the dep region. They just cancel numerically. (What 'near' means will be clear when study further- just take it for granted now that this happens. Otherwise you'll confuse yourself.) | |

Electron and hole transport occurs because of two mechanisms- one is DIFFUSION, which occurs because of difference in concentration in space. The other is DRIFT-electron/hole movement under application of electric field. | |

You are saying that near the points of the depletion region electrons are still going back and forth due to the electric field....but not like across and into the regions (cause if so.....why would we call it a depletion region?) | |
