MCQ
At absolute zero, $Si$ acts as
  • A
    non metal
  • B
    metal
  • semiconductor
  • D
    none of these

Answer

Correct option: C.
semiconductor
c
Pure silicon, at absolute zero, will contain all the electrons in bounded state. The conduction band will be empty. So there will be no free electrons (in conduction band) and holes (in valence band) due to thermal agitation. Pure silicon will act as insulator.
