Question

Identify the property which is not characteristic for a semiconductor –

• A. At a very low temperatura it behaves as aninsulator
• B. At highertemperaturetwotypes of chargecarrierswill cause conductivity
• C. The charge carriers are electrons and holes in the valence band at higher temperature
• D. The semiconductor is electrically neutral

Answer 1

Answer: (C)

The charge carriers are electrons and holes in the valence band at higher temperature

Answer 2

e^– exist in conduction band & holes in valence band.
