This is utterly vague if you do not put this question in its context. If you wish that other put in time and effort to produce a thoughtful response, you should at least put in some effort to present a clear and concise question.

Is this question about the physics of vacuum tube electronics?

This is why we have to wait for the OP to come back and provide a more complete explanation. I could easily say that this is a question of charge extraction out of a photocathode as well!

Or perhaps he is referring to the reverse leakage current of a semiconductor junction?
