12. Take a p-n junction where the p-type semiconductor is on the left side of the junction. lfthere is a forward bias in the left-to-right direction of the crystal (i.e. p-typc is connected to the positive terminal) (a) current ow is appreciable (b) current ow is minimal (c) the DC current is rectied to AC (d) current ow is zero (e) the electrons become superconducting 13. The intrinsic conductivity of pure silicon at 20C is 5X10\" J'Qm (very low) and the band-gap energy is 1.11 eV. At what temperature is the intrinsic conductivity 2000>
