Question

We are familiar with the semiconductors Silicon and Germanium.
a) Draw the energy bands of a $n$-type semiconductor.
b) The following figure represents a _______.

Answer 1

(b) Energy band diagram for n-type semiconductor is shown in the attached diagram. Additional donor levels are present in n-type semiconductor near the conduction band which increases the overall conductivity of semiconductor.

(c) The symbol shown in the problem is of a p-n junction diode.
