Define mobility of charge carrier
WebJun 27, 2024 · The mobility of charge carriers in dielectric liquids is not only an intrinsic parameter of the conduction process, but it also can define the pre-breakdown … WebElectrons and holes are mobile charge carriers. The mobility of electrons is 2.5 to 3 times the mobility of holes. The mobility of electrons and holes depends on their effective masses. The effective mass of electrons is less than that of holes hence electrons have higher mobility than holes. Ge.

WebThe charge carrier in most metals is the negatively charged electron (see electron scattering). Mobility is formally defined as the value of the drift velocity per unit of … In solid-state physics, the electron mobility characterises how quickly an electron can move through a metal or semiconductor when 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. Electron and hole mobility are special cases of electrical mobility of charged particles in a fluid under an applied electric field.
