10 Facts About Electron mobility

The term carrier mobility refers in general to both electron and hole mobility.

Electron and hole mobility are special cases of electrical mobility of charged particles in a fluid under an applied electric field.

Therefore Electron mobility is a very important parameter for semiconductor materials.

Almost always, higher Electron mobility leads to better device performance, with other things equal.

Semiconductor mobility depends on the impurity concentrations, defect concentration, temperature, and electron and hole concentrations.

Usually, the electron drift velocity in a material is directly proportional to the electric field, which means that the electron mobility is a constant.

Where is a Electron mobility prefactor, is activation energy, is the Boltzmann constant, and is temperature.

Where is a Electron mobility prefactor, is a parameter that quantifies the width of localized states, and is the dimensionality of the system.

Electron mobility can be calculated from time-resolved terahertz probe measurement.

Proxy for charge carrier Electron mobility can be evaluated using time-resolved microwave conductivity.
