This chapter can be divided into following categories:- Classification Types of Semi-Conductors p-n junction diode Biasing of Diode Rectifiers Special Diodes (Zener, Photodiode, LED and Solar Cell) Transistors Logic Gates Communication System In the next few posts I will be posting in the same manner ie. (in bullets form) for your convenience and I hope that helps you in completing your syllabus. Classification Materials can be classified on the basis of conductivity as Conductors, Insulators and Semi Conductors. The basic difference among all the three is the difference of energy in between the Conducting and the Valence band. This can be seen here. Note- The range of conductivity should be kept in mind. For Semi-Conductors the energy difference is not very large but not even very less. So by providing proper conditions they can show conductivity. Types of Semi-Conductors Further we can say that there are two other types of semi con...
