This term is used frequently to describe the mechanism of current flow in a forward biased PN junction. It is called "recombination current", where recombination is the process of conduction electrons filling holes in the valence band, thus eliminating an electron-hole pair.
The issue with this terminology, is that elimination of an electron-hole pair seems to stop current, not cause or allow it. So to call a current "recombination current" makes it seem as though the current is made up of disappearing electrons and holes, a seeming contradiction. You could as well say that at rush hour on the highway, the traffic is made up of "parking traffic".
So with this in mind, how is the phrase "recombination current" supposed to be interpreted? In effect, what is recombination current through a PN junction?
