Mobility =(Vd/E)=(D r i f t v e l o c i t y/E l e c t r i c f i e l d) =([LT- 1]/[MLT- 3 A- 1]) =[M- 1 L0 T2 A1]

Q. The dimensional formula of electron mobility in semiconductor is ______.

$[M^{- 1} L^{1} T^{2} A^{1}]$

$[M^{1} L^{0} T^{- 2} A^{- 1}]$

$[M^{1} L^{- 1} T^{- 2} A^{- 1}]$

$[M^{- 1} L^{0} T^{2} A^{1}]$

Mobility $= \frac{V _{d}}{E} = \frac{Dr i f t v e l oc i t y}{El ec t r i c f i e l d}$
$= \frac{[ L T ^{- 1} ]}{[ M L T ^{- 3} A ^{- 1} ]}$
$= [M^{- 1} L^{0} T^{2} A^{1}]$

Q. The dimensional formula of electron mobility in semiconductor is ______.

[M−1L1T2A1]

[M1L0T−2A−1]

[M1L−1T−2A−1]

[M−1L0T2A1]

Mobility =EVd​​=ElectricfieldDriftvelocity​ =[MLT−3A−1][LT−1]​ =[M−1L0T2A1]

$[M^{- 1} L^{1} T^{2} A^{1}]$

$[M^{1} L^{0} T^{- 2} A^{- 1}]$

$[M^{1} L^{- 1} T^{- 2} A^{- 1}]$

$[M^{- 1} L^{0} T^{2} A^{1}]$

Mobility $= \frac{V _{d}}{E} = \frac{Dr i f t v e l oc i t y}{El ec t r i c f i e l d}$
$= \frac{[ L T ^{- 1} ]}{[ M L T ^{- 3} A ^{- 1} ]}$
$= [M^{- 1} L^{0} T^{2} A^{1}]$
