The difference between insulator and semiconductor is   a. wider gap between valence and conduction band b. the number of free electrons c. the atomic structure d. all of the above

Q1) a)Explain how doping a pure silicon crystal with donor impurity atoms makes more charge carriers available for conduction.b)Does the above doping result in a p-type or n-type semiconductor? Explain your answer.                                      c) When the diode is forward biased:i) What happens to the barrier potential?ii) What happens to the depletion region?iii) Indicate on your diagram the directions in which the holes and electrons move

C and D please
