What is the difference between electron mobility and hole mobility?
The drift velocity of an electron for a unit electric field is known as the mobility of the electron. electron mobility characterizes how quickly an electron can move through a metal or semiconductor when pulled by an electric field. The mobility of an electron can be calculated by: μ = V d / E
The average velocity with which a given ion drifts through a specified medium under the influence of an electric field is called ionic mobility.
Aug 29, 2023 · The motion of the ion itself can be characterized by charge, shape, and size. The ion moves through the medium and migrates with a characteristic velocity, which is in turn dependent on the characteristics of the ion itself and the properties of the medium. This phenomenon is called electrophoresis.
In solid-state physics, the electron mobility characterises how quickly an electron can move through a metal or semiconductor when pushed or pulled by an electric field. There is an analogous quantity for holes, called hole mobility. The term carrier mobility refers in general to both electron and hole mobility.

Definition of Ionic mobility ( μ) Ionic mobility describes the speed of an ion in an electrolyte moving on passage of electricity current between two electrodes with a unit value of potential gradient. It is denoted by a symbol ‘ ‘. Speed is the distance travelled in the unit time.
Nov 11, 2021 · Ion mobility spectrometry is increasingly often coupled to mass spectrometry measurements, either for separation purposes or to assist compound identification. This chapter introduces basic definitions and concepts underlying ion mobility spectrometry.
Ion mobility. Qualitatively: Large ions in viscous liquids can be expected to be drifting slowly and have low conductivities. Quantitatively: drift velocity. electric field strength. s = uE. ion mobility. Two forces are acting on the ion: F = zeE. field elementary charge. Stokes’ law F = number of ion charges. retardatio n. 6 πη rs.
