Mobility of electrons in semiconductor is defined as the ratio of their drift velocity to the applied electric field. If, for an 
-type semiconductor, the density of electrons is 
and their mobility is 
then the resistivity of the semiconductor (since it is an n-type semiconductor (since it is an 
-type semiconductor contribution of holes is ignored) is close to :
