What does the Stokes-Einstein equation represent?

The Stokes-Einstein equation is the equation first derived by Einstein in his Ph. D thesis for the diffusion coefficient of a “Stokes” particle undergoing Brownian Motion in a quiescent fluid at uniform temperature.

What is Einstein’s relationship for semiconductor?

According to Einstein’s relationship for a semiconductor, the ratio of the diffusion constant to the mobility of the charge carriers is. Equal to one and is equal to the volt equivalent of the temperature.

What is K in Einstein?

Electrical mobility equation is the electron temperature or ion temperature in plasma (K).

How do you calculate mobility diffusion coefficient?

µ = (q/kT)D In this equation, µ is the mobility, q is the electrical charge, k is the Boltzmann constant, T is the temperature of the gas, and D is the diffusion coefficient.

Which two quantities are related by Einstein relation?

6) At high temperatures, the mobility decreases because: a) Lattice vibrations scatter the electrons. 8) The Einstein relation relates what two quantities? a) The diffusion coefficient and the minority carrier lifetime.

What are Einstein coefficients derive a relation between them?

The Einstein coefficients are fixed probabilities per time associated with each atom, and do not depend on the state of the gas of which the atoms are a part. Therefore, any relationship that we can derive between the coefficients at, say, thermodynamic equilibrium will be valid universally.

What kind of energy is E mc2?

In the equation, the increased relativistic mass (m) of a body times the speed of light squared (c2) is equal to the kinetic energy (E) of that body. Brian Greene kicks off his Daily Equation video series with Albert Einstein’s famous equation E = mc2.

What is Navier-Stokes equation and why it is so important explain?

Navier-Stokes equation, in fluid mechanics, a partial differential equation that describes the flow of incompressible fluids. The equation is a generalization of the equation devised by Swiss mathematician Leonhard Euler in the 18th century to describe the flow of incompressible and frictionless fluids.
