16-1. Consider a conduction electron in copper (Cu). The wave vector of the electron points in the [100] direction. The magnitude of its wave vector is k=[01] ____________ /Angstrom. We apply an electric field E=1.00 V/m in a negative [100] direction. If the electron could travel without hindrance (no collisions), how long would it take to reach the boundary of the first Brillouin zone? You may use Fig. 8-11 on p. 68 in the textbook to determine how far the electron must travel in k space to reach the boundary of the first Brillouin zone.
