A) a perfect conductor
B) a super conductor
C) a semiconductor
D) a perfect insulator
Correct Answer: D
Solution :
Semiconductors \[(Ge)\] has four valence electrons. At 0 K all atoms of \[Ge\] forms covalent bonds with the four valence electrons around it, due to this sharing of electrons the atom achieves a stable configuration. Thus, no electrons is free for conduction. Hence conduction of electricity is not possible through semiconductors and it behaves as a perfect insulator.You need to login to perform this action.
