The variation of drift velocity with the electric field for most of the semiconductor (except Ga AS) is as shown:
The initial slope of this curve gives the mobility of electrons:
\({\mu_n} = \left( {\frac{{{v_d}}}{E}} \right)\)
Analysis:
vd = 100 m/s
E = 200 V/m
\({\mu_n} = \left( {\frac{{{v_d}}}{E}} \right)\)
= \(\frac{100}{200} = 0.5 \) m2 / V-s
