Bias Characteristics of PN Junction Diode
Forwarding Bias Characteristics of PN Junction Diode
The circuit for the study of forwarding bias characteristics of PN junction diode is shown in Fig a....
PN Junction diode
PN Junction diode:
If one side of a single crystal of pure semiconductor (Ge or Si) is doped with acceptor impurity atoms and the other...
Extrinsic Semiconductor
An extrinsic semiconductor is one in which an impurity with a valency higher or lower than the valency of the pure semiconductor is added,...
Intrinsic Semiconductor
A semiconductor which is pure and contains no impurity is known as an intrinsic semiconductor. In an intrinsic semiconductor, the number of free electrons...
Definition: Insulators, Semiconductors & Conductors
Insulators:
In an insulator, the forbidden energy gap is very large. In general, the forbidden energy gap is more than 3eV and almost no electrons...
Energy bands in conductors
The lower completely filled band is called valence band and the upper empty band is called conduction band. The gap between the top of...
Energy band in solids
In solids, the atoms are arranged in a systematic space lattice and each atom is influenced by neighbouring atoms. The closeness of atoms results...
Classification of Metals, Conductors and Semiconductors
On the basis of conductivity: On the basis of the relative values of electrical conductivity (σ) or resistivity (ρ = 1/σ), the solids are...
