The conductivity of Au is $5 \times 10^5 \text{ /ohm.cm}$ while the electron concentration is known to be $5.9 \times 10^{22} \text{/cm}^3$. Evaluate the corresponding value of $\langle \tau \rangle_n$, the mean free time between scattering.

Step 1
Step 1: Recall the formula for mean free time (t) between scattering: t = 1 / (n * σ * v) where: - n is the number density of particles - σ is the scattering cross-section - v is the average velocity of the particles Show more…
