Unformatted text preview: VI. Find out the thermal velocity of electrons in GaAs at room temperature i. e. the velocity of electrons with an energy of kT 2 3 . Compare it with the final ballistic velocity in Problem V and explain the significance of the comparison. VII. A silicon sample is doped with 3 16 10 cm borons, estimate the conductivity of this sample at room temperature if we can neglect impurity scattering. (It is still a good approximation in this case) VIII. Estimate the mean free time and mean free path of the holes in Problem VII. --END-- Electrical Engineering Department The Henry Samueli School of Engineering and Applied Science University of California, Los Angeles Dee-Son Pan firstname.lastname@example.org Phone (310)-825-1123 Spring 2008...
