In simple terms, the knee voltage of a crystal diode is approximately equal to its impedance.
The problem is that in the real world, the impedance of a diode is not constant, but varies depending on a number of factors, including the temperature, the material in which the diode is made, and the frequency of the voltage applied to it. The knee voltage of a crystal diode varies as a result of the impedance.
In other words, if you are going to make an audio amplifier, for example, you should use a diode with the appropriate knee voltage to give it the right sound.
The knee voltage in any diode is the amount of frequency that the diode makes, not the voltage that’s applied to it. So, when you get to the right temperature, you can apply a knee voltage to the crystal diode and it can be made to go more or less high.
If you’re not using a crystal diode, then you can’t apply a knee voltage to it, because unless you’ve made one, you can’t use any of its components.

It’s probably not a coincidence that most crystal diode companies are located in countries where the voltage you need to use in a crystal diode is at least a little bit above the knee voltage. If you have a crystal diode that works at a particular knee voltage, you should be able to apply a knee voltage to it and it should be able to charge up.
It sounds like a great idea. Personally, I would prefer to buy a crystal diode and use that as a source of voltage for charging up the voltage on it. Because I think it also has a much lower failure limit than a standard crystal diode, it works better than a standard diode.
When I ask a physicist, “Could you give a crystal diode a greater resistance than a diode?” He replies “Yes, but it’s not as good for the environment as a diode.
