i) The equation above contains really only three variables in it: Id, Vd, and T. All the other terms are constants. Since in most cases we assume temperature is fairly constant as well, we are really only dealing with two variables: diode current and diode voltage. Based on this realization, re-write the equation as proportionality rather than equality, showing how the two variables of diode current and voltage relate ii) Based on this simplified equation, what would an I vs V graph for a PN junction look like? How does this graph compare against the I vs V graph for a resistor? iii) When "P" and "N" type semiconductor pieces are brought into close contact, free electrons from the "N" piece will rush over to fill holes in the "P" piece, creating a zone on both sides of the contact region devoid of charge carriers.
