Question

In semiconductor physics, a common alternative unit for mobility is:

Options

• \[cm^2s^{-1}V\]

• \[cm^2Vs^{-1}\]

• \[cm^2V^{-1}s^{-1}\]

• \[mm^2V^{-1}s^{-1}\]

Answer 1

While the SI unit is \[m^2V^{-1}s^{-1}\], semiconductor physics commonly uses \[cm^2V^{-1}s^{-1}\] for convenience when dealing with typical mobility values in semiconductors. The conversion factor is 10^4 since 1 m² = 10⁴ cm².
