An "isotype" step junction is one in which the same impurity type doping changesfrom one concentration value to another value. An n-n isotype doping profi le is shownin Figure P7.12.

(a) Sketch the thermal equilibrium energy-band diagram of theisotype junction.

(b) Using the energy-band diagram, determine the built-in potentialbarrier.

(c) Discuss the charge distribution through the junction.An "isotype" step junction is one in which the same impurity type doping changes from one concentration value to another value. An n-n isotype doping profi le is shown in Figure P7.12.
