Identify the mismatched pair from the following
`{:("(a) Zener diode",:,"voltage regulator"),("(b) germanium doped with phosphorous",:,"n-type semiconductor"),("(c) semiconductor",:,"band gap > 3 eV"),("(d) p-n junction diode",:,"rectifier"),("(e) silicon doped with aluminium",:,"p-type semiconductor"):}`

Text Solution

Verified by Experts

The correct Answer is:
C
The band gap of semiconductor is less. than 3 eV. So, option (c) is mismatch.
