Electron and hole mobility are special cases of electrical mobility of charged particles in a fluid under an applied electric field. Meer weergeven 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. … Meer weergeven Drift velocity in an electric field Without any applied electric field, in a solid, electrons and holes move around randomly. Therefore, on average there will be no overall motion of charge carriers in any particular direction over time. However, … Meer weergeven Recall that by definition, mobility is dependent on the drift velocity. The main factor determining drift velocity (other than effective mass Meer weergeven While in crystalline materials electrons can be described by wavefunctions extended over the entire solid, this is not the case in systems with appreciable structural disorder, … Meer weergeven Typical electron mobility at room temperature (300 K) in metals like gold, copper and silver is 30–50 cm / (V⋅s).
