electric field in a pn junction

[islahuxley]

Hello folks. I joined yesterday !

I'm writing a report for Higher Physics (college stuff)...

I some how didn't learn properly about electric fields. When i try to describe what forward bias is my teacher has hinted that i need to include discussion or mention of an electric field.

I've mentioned the charge barrier and the pd of the depletion zone but what I'm trying to say is that fwd bias is when the negative end of the battery connects to n type region and so on. Electrons repel and so on. I'm really lost. I've spent days looking online and i can't get it in enough detail to understand. I have mild dyspraxia in that my weakest area is organising sentences. Plus I've never written a report like this where you get marked down for saying terms that are too high level and can't say too much (word count). It makes it even harder for me.

Any links or baby talking would be appreciated, thankyou so much.
