Can you help me with the script of the following homework:

Prepare a 3-minute-long video of yourself, where you explain the working principle of pn junction. In your video please include the following points:

 

·        How does pn junction form (open-circuit pn junction)

·        How does pn junction diode operate under forward bias

·        How does pn junction diode operate under reverse bias

·        How does pn junction diode operate in breakdown

There is a strict rule against plagiarism if you can help me to build a script according to the aforementioned directions that would be very helpful, thanks.
