Why does the voltage drop across a diode change with increasing current?

[QUOTE="Alex Myhill, post: 5463931, member: 584586"] [h2]Homework Statement [/h2] I have recently performed an experiment where the voltage drop and current through a diode were measured. I am wondering why the voltage drop across the diode changes. Theoretically, the voltage drop should stay the same as there is a certain amount of energy required to get past the depletion zone at the junction of the P-doped and N-doped silicon. Why then does the voltage drop change as the current increases? [h2]Homework Equations[/h2] There are no relevant equations for this question. [h2]The Attempt at a Solution[/h2] Does the voltage possibly increase due to the increase charge in the diode as the current increases? I am really not sure as everywhere I have read states that the voltage drop shouldn't change. [/QUOTE]
