Define the term 'mobility' of charge carriers. Write its S.I. unit. |
|
Answer» Solution :Mobility is defined as the magnitude of the DRIFT velocity per UNIT electric field. `mu=(|V_d|)/E=(alphatau)/E=(eE)/m TAU/E=e/m tau` where`tau` is the average collision time for electrons. The SI unit of mobility is `m^2//Vs` or `m^2V^(-1)S^(-1)` |
