I've just had my first lecture on transistors and we have been asked a couple of questions to see if we understand the basics. However, I'm not confident even with these.
1) For an NPN transistor without any external voltage, what is the electric field direction within the B-E and B-C junctions?
My understanding is that the electric field directions are from E to B and from C to B.
2) For an NPN transistor without any external voltage, what is the diffusion current direction within the B-E and B-C junctions?
My understanding is that the diffusion current was from E to B and then from B to C.
Are either or both of these correct?
