Semiconductor Important Questions

Question 1: Name two factors on which the electrical conductivity of a pure semiconductor at a given temperature depends.

Question 2: How does the conductivity of a semiconductor change with the rise in temperature?

Question 3 : Why is germanium preferred over silicon for making semiconductor devices?

Question 4 : Why is the conductivity of n-type semiconductor greater than that of the p-type semiconductor even when both of these have the same level of doping?

Question 5: Can two PN junction diodes placed back-to-back work as a PNP transistor?
