# I-V-Characteristics of Junctions with Diffusion and Generation Currents

| I-V-characteristics of pn-junctions should be basic knowledge. However, it is not a particularly easy subject.
|  | The "ideal junction", without consideration of what happens in the space charge region, is not too difficult. Including diffusion and generation currents from the SCR, however, makes things quite messy. A proper treatment besides involving some knowledge of "Shockley-Read-Hall recombination theory" still must cut a lot of corners by using all kinds of approximations.
| If you are not too familiar with these topics, you may want to read up about it in the Hyperscript "Semiconductors". Here are the links:
|  | Simple treatment of pn-junction (including SCR part)
|  | More involved treatment of simple pn-junction
|  | Shockley-Read-Hall recombination
| More links will be found in these modules.
