Question
Physics Question on Semiconductor electronics: materials, devices and simple circuits
Identify the mismatched pair from the following
A
Zener diode : voltage regulator
B
germanium doped with phosphorous : n-type semiconductor
C
semiconductor : band gap > 3eV
D
pn junction diode : rectifier
Answer
semiconductor : band gap > 3eV
Explanation
Solution
The band gap of semiconductor is less than 3eV. So, option (c) is mismatch.
