In pure intrinsic semiconductor, the concentration of electrons is equals to concentration of holes.…

Question 4 If a pure ("intrìnsic") semiconductor material is heated, the thermal energy liberates some valence-band electrons into the conduction band. The vacancies left behind in the valence band are called holes: Conduction band Valence band Increasing electron energy If an electrical voltage is applied across the heated semiconducting substance, with positive on the left and negative on the right, what will this do to the energy bands, and how will this affect both the electrons and the holes? -
