The effective mass of an electron in a crystal is 0.1m₀. What is the mobility if the relaxation time is 10^(-13) s?
Q1. The effective mass of an electron in a crystal is 0.1m₀. What is the mobility if the relaxation time is 10^(-13) s?
Answer: 1.76 m²/Vs
Explanation: Using μ = eτ / m*, we get μ = (1.6 * 10^(-19) * 10^(-13)) / (0.1 * 9.1 * 10^(-31)) = 1.76 m²/Vs.
