## Materials Science and Engineering: An Introduction

$µ_{e}$ = 5.57 x $10^{-3}$ $\frac{m^{2}}{Vs}$
Required: electron mobility, $µ_{e}$ Solution: Using Equation 18.8, $µ_{e}$ = $\frac{σ}{n|e|}$ = $\frac{6.8 \times 10^{7} (Ωm)^{-1}}{(7.62 \times 10^{28} m^{-3})(1.602 \times 10^{-19}C)}$ $µ_{e}$ = 5.57 x $10^{-3}$ $\frac{m^{2}}{Vs}$
