Before an electron can participate in the conduction of electricity, it must leave from the valence band and transfer to the conduction band.
Transferring to the conduction band involves energy acquisition by an electron from external sources and this energy must be greater than the energy gap of the material.
Which semiconductor material has the highest energy gap?
A. Zinc Sulfide (ZnS)
B. silicon (Si)
C. germanium (Ge)
D. Indium Antimonide (InSb)
