(a) Semiconductors are materials which have a conductivity between conductors. Based on your
knowledge, describe at least three particles that make up the atom and briefly describe the
difference between n-type and p-type semiconductor materials. Classify the three particles
that make up the atom and briefly describe the difference between n-type and p-type
semiconductor materials.
(b) Figure 1 shows a basic diode with p-type and n-type semiconductors with complete Voltage
Bias. Identify the depletion region when the diode is conducted in reverse bias. With the
aid of suitable diagram, briefly explain the region occur when the 5 V supply voltage is
аpplied.

(c) Figure 2 shows the class of materials based on relative comparisons. Based on Figure 2
description, identify the materials that affected the conduction and valence band. As an
engineer, explain the consequences if the atomic number of a neutral atom is 8, and the
maximum number of electrons in the 3rd shell of an atom.
