WebAug 7, 2024 · E GO indicates the value of E G at T – 0 0 K. Thus, E GO is equal to 0.785 (1.21) eV for Ge (Si). From equations (15) and (16), we find that E G at room temperature is 0.72 (1.1) eV for Ge (Si). Mobility The mobility of a charge varies as T -m over temperature range of 100 to 400 K. 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 … See more 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 … See more Typical electron mobility at room temperature (300 K) in metals like gold, copper and silver is 30–50 cm / (V⋅s). Carrier mobility in … See more Recall that by definition, mobility is dependent on the drift velocity. The main factor determining drift velocity (other than effective mass) is scattering time, i.e. how long the carrier is ballistically accelerated by the electric field until it scatters (collides) with … See more The charge carriers in semiconductors are electrons and holes.
