Question Description:

25.50

The conduction band of a simple cubic lattice with cubic edge a is given by : E(k)=Eo (3 – cosKxa – cosKya – cosKza). In the absence of any scattering, find the trajectory of an electron in real space under a uniform, time-independent electric field E in the x-direction. Assume that the electron is at rest with k = 0 at time t = 0. Describe the trajectory by x(t), y(t), z(t), and plot them.
