Statement -1 : Band gap in germanium is small, because
Statement -2 : The energy spread of each germanium atomic energy level is infinitesimally small.
Text Solution
Verified by ExpertsThe correct answer is:
C
Statement -1 : G ermanium is a semiconductor, where the energy gap between adjacent bands is sufficiently small for thermal energy to be able to promote a small number of electrons from the full valence band to the empty conduction band. This leaves both bands partially filled, so the material can conduct electricity.
Statement -2 : Incorrect statement.
