Mobility is formally defined as the value of the drift velocity per unit of electric field strength; thus, the faster the particle moves at a given electric field strength, the larger the mobility. Hope it helps ☺☺☺

Mobility of the charge carrier is defined as the drift velocity of the charge carrier per unit electric field.

It is denoted by m and is given as

The SI unit of m is m² V⁻¹ s⁻¹.

In 1785 the French physicist Charles Augustin Coulomb measured the electric force between small charged spheres using a torsion balance. He then formulated his observations in the form of Coulomb's Law. Coulomb's Law is an electrical analog of Newton's Universal Law of Gravitation. It states that

The force of attraction or repulsion between two stationary point charges is
(i) directly proportional to the product of the magnitude of two charges.
(ii) inversely proportional to the square of the distance between them.
This force acts along the line joining the two charges.

Yogita Ingle 6 years, 2 months ago

Dipole constant is the measure of the ease with which an electric dipole to align itself in the direction of electric field. Now, with increase in temperature the kinetic energy of particles constituting the dipole increases and the vibration in the dipole as a whole increases. So, it becomes more difficult for it to align itself with the external field. This results in the reduction of the dipole constant.

<th>BASIS OF DIFFERENCE</th> <th>p TYPE SEMICONDUCTOR</th> <th>n TYPE SEMICONDUCTOR</th>

Group of Doping Element	In P type semiconductor III group element is added as doping element.	In n type semiconductor V group element is added as doping element.
Nature of Doping Element	Impurity added creates vacancy of electrons (holes) called as Acceptor Atom.	Impurity added provides extra electrons and is known as Donor Atom.
Type of impurity added	Trivalent impurity like Al, Ga, In etc. are added.	Pentavalent impurity like P, As, Sb, Bi etc. are added.
Majority Carriers	Holes are majority carriers	Electrons are majority carriers
Minority Carriers	Electrons are minority carriers	Holes are minority carriers
Density of Electrons and Holes	The hole density is much greater than the electron density. nh >> ne	The electron density is much greater than the hole density. ne >> nh
Energy level	The acceptor energy level is close to the valence band and away from the conduction band.	The donor energy level is close to the conduction band and away from the valence band.
