The book is a compilation of lecture notes for an Electrical and Electronic course. The electronic system is an electric circuit that uses electronic devices to produce digital operating systems. Materials used in electronic devices mostly are semiconductors. The most widely use of semiconductors are silicon and germanium. By doping with the trivalent and pentavalent atom, the silicon and germanium will be a good semiconductor in electronic systems.
Upon completion of this lesson, students should be able to acknowledge the electronic systems, describe the atomic structure of the silicon and germanium atom and explain the differences between holes and electrons. They should also be able to explain the effect of adding certain impurity atoms to change the conduction characteristics of semiconductor and describe the following types of trivalent, pentavalent, Donor/acceptor, n-material & p-material.

Excerpt from the Book
The p-n junction
A p-n junction is piece of semiconductor material in which part of the material is p-type and part is n-type. In order to examine the charge situation, assume that separate blocks of p-type and n-type materials are pushed together. Also assume that a hole is a positive charge carrier and that an electron is a negative charge carrier. At the junction, the donated electrons in the n-type material, called majority carriers, diffuse into the p-type material and the acceptor holes in the p-type material diffuse into the n-type material as shown by the arrows in Figure 2.2. Because the n-type material has lost electrons, it acquires a positive potential with respect to the p-type material and thus tends to prevent further movement of electrons. The p-type material has gained electrons and becomes negatively charged with respect to the n-type material and hence tends to retain holes.
