Unformatted text preview: VI. The conduction band of GaAs has an effective mass of 0.067 m , where m is the free electron mass. Find out the curvature of the conduction band at the band edge. VII. If the electron in GaAs is accelerated from rest by an electric field of 1 kV/cm in 2 picoseconds, find out the final velocity of the electron and how long it has traveled. VIII. From the atomic configuration of copper and energy band theory, explain haw many valence electrons per atom is making contribution to the conductivity of copper crystal? --END-- Electrical Engineering Department The Henry Samueli School of Engineering and Applied Science University of California, Los Angeles Dee-Son Pan email@example.com Phone (310)-825-1123 Spring 2008...
