Electronic Devices

Construction of bipolar junction transistor is discussed here. You will know about the detail construction of pnp and npn transistors.

This study material contains well-written notes of diodes. You will know about the properties of diodes. How diode acts in forward and reverse bias are discussed here.

Construction of semiconductor, properties of semiconductor, types of semiconductor are discussed here. Fermi level concept is also introduced to clear the concept of p-type and n-type semiconductor.
