Option 3 : Mobility

In a semiconductor, the movement of charge carriers under the influence of an electric field is called drift.

Mobility is defined as the value of the drift velocity of the charge carrier per unit of electric field strength. Thus, the faster the particle moves at a given electric field strength, the larger the mobility.
