I have read some answers about how BJTs work, but I'm still not convinced.
To show my doubts better, suppose we extract base and collector from BJT NPN transistor with all its construction details (thin base, doping things, etc.). Let's treat it like odd diode and connect it reverse biasaed way to a battery.
Would electrons from battery minus clip diffuse through P material (is there chance this strange diode would conduct)? I mean why in diode reverse biasing stops current, but in BJT doesn't do the same? What helps transferring electrons through depletion region?
