A question with illustration

[lucky6969b]

I never come across this kind of diagram
in any other texts. Does anything like this really exist in electronics...Thanks

I think they are called "transistors", maybe you have heard of them.

I know, I know, but I haven't seen such a transistor diagram that
represents them as charge profile before...
Any ideas?
Thanks

The charge profile diagram represents a BJT transistor.

Yes this is a NPN transistor. The slanted line shows the minority carrier density in the base region dropping towards the collector. They are trying to show how varying the collector voltage affects the collector current, i.e. Early voltage.
