electron diffusivity

The electron mobility μn in a non-degenerate germanium semiconductor at 300 K is 0.38 m²/Vs. The electron diffusivity Dn at 300 K (in cm²/s, rounded off to the nearest integer) is...

The electron mobility $\mu_n$ in a non-degenerate germanium semiconductor at 300 K is $0.38 \mathrm{~m}^2 / \mathrm{Vs}$. The electron diffusivity $D_n$ at 300 K (in $\mathrm{cm}^2...
