PN Junctions and breakdown
1. Draw and interpret energy band diagram for pn junction inequilibrium, forward, and reverse bias
2. Describe what physically happens (And why) when you put n-Siin contact with p-Si (e.g., junction formation)
3. Calculate Vo, W, Wn, Wp
4. Describe how/why current flows in forward and reversebias.
5. Utilize law of junction to calculate the minority carrierconcentration just outside the depletion layer
6. Quantify the forward and reverse bias current in a p-njunction given appropriate information
7. Describe the meaning of the diode ideality factor for valuesof 1 and 2 and in between
8. Describe what constitutes “short diode†conditions
9. Calculate the depletion layer capacitance given sufficientinformation
10. Identify the two mechanisms that allow for reverse biasbreakdown of a diode.
11. Describe what occurs during Zener tunneling and avalancheand the conditions that this will occur
