DIODE - Coggle Diagram

- - - - When voltage is applied in opposite direction accross diode, depletion region begins to shrink.
      - It ensures electrons and holes move toward the junction as they are repelled from +ve and -ve terminals of voltage source
      - Given enough applied voltage, both holes and electrons would overcome depeltion region and meet near the junction
    - - If a voltage is applied across the diode, electrons from the external circuit would create more -ve ions in the p-type region by "filling the holes" and more +ve ions would be created in the n-type region as electrons are displaced toward the positive terminal of the voltage source
      - Depletion region would increase and the voltage between the p-type and n-type regions would also increase as the total charge on each side of the junction increases in magnitude until the voltage across the diode equals and opposes the applied voltage and cancels it out, ceasing the current through the circuit.
