-3 (a) Assume that n-type Si semiconductor with dopant concentration of 2.8*1015 cm3 is used for a photoconductor at 300 K. Under illumination, the excess carrier concentrations are An= = 4p = 8x1014 cm ?. Calculate the quasi-Fermi energy level Fn relative to Efi. (b) For a p-i-n photodetector, briefly explain “I” region and the operation condition of p-i-n photodiode.
