PROCESSING QUESTION:
1. How does the semiconductor diode is form?
- When two P-Type and N-Type semiconductors are joined together, a diode is
generated. The P-Type semiconductor is positive in charge and has an excess
of holes. An excess of electrons exists in the N-Type semiconductor.

APPLICATION
1. What device that can closely approximate a diode?
- The “diode model” or “diode equivalent circuits” are mathematical models
used for the approximation of diode’s actual behavior.

ASSESSMENT
A. Discussion Question.
1. How does the majority carrier in a diode behave during no bias, forward bias and reverse
bias?
- During no biased, the number of majority carriers is having a bulk in the n-type material
that there will invariably be a small number of majority carriers with sufficient kinetic
energy to pass through the depletion region into the p-type material. While, In Forward
biased the majority charge carriers move across the junction so that a large current can
flow. And for Reverse biased, its widen the depletion region and a depletion of majority
carriers.
