If we mix a pentavalent impurity in a crystal lattice of germanium, what type of semiconductor formation will occur?
Options
- Ap-type
- Bn-type
- CBoth (a) and (b)
- DNone of the two
Correct answer
B. n-type
Step-by-step solution
On adding a pentavalent impurity with germanium, we get n -type of semiconductors because excess of electrons is responsible for conduction.
