Which of the following is not associated with a p-n junction?Charge storage capacitanceJunction capacitanceChannel length modulationDepletion capacitance

To determine which option is not associated with a p-n junction, let's analyze each choice:

1. Charge Storage Capacitance: This relates to the ability of a junction to store charge. It is associated with p-n junctions, particularly in the context of how minority carriers are stored in the depletion region.

2. Junction Capacitance: This is indeed associated with p-n junctions and describes the capacitance related to the depletion region of the junction, which changes with the applied voltage.

3. Channel Length Modulation: This is a phenomenon related to MOSFET devices rather than p-n junctions. It describes how the effective length of the channel in a MOSFET reduces with an increase in the drain-source voltage, which affects the current flow in the device.

4. Depletion Capacitance: This is also a capacitance associated with p-n junctions, arising from the charge separation in the depletion region.

Conclusion

Based on the analysis, the correct choice is Channel Length Modulation, as it is not associated with a p-n junction.
