Question

13. Consider a one-dimensional chain of atoms with lattice constant a. The energy of an electron with wave-vector k is $\mathcal{E}(k) = \mu - \gamma$, where $\mu$ and $\gamma$ are constants. If an electric field E is applied in the positive x - direction, find the time-dependent velocity of an electron.

Step 1

The equation of motion is given by: m * dv/dt = q * E where m is the mass of the electron, dv/dt is the time derivative of the velocity, q is the charge of the electron, and E is the electric field. Show more…
