Question
The binary compound AlP (aluminum phosphide) is isoelectronic with the intrinsic semicinductor Si. Which of the following statements best describes the band gap energy of AlP?
options:
AlP has a band gap energy that is the same as that of Si.
AlP has a smaller band gap energy than Si.
AlP has a larger band gap energy than Si.
The band gap energy of AlP cannot be predicted relative to that of Si.
A.AlP has a band gap energy that is the same as that of Si.
B.AlP has a smaller band gap energy than Si.
C.AlP has a larger band gap energy than Si.
D.The band gap energy of AlP cannot be predicted relative to that of Si.
Explanation / Answer
AIP has a band gap larger than silicon
AIP has a band gap of 2.5 eV
Nd silicon has a band gap of 1.1eV.
So option (c) is correct.
