EL ENG 143 Study Guide - Midterm Guide: Relative Permittivity, Silicon Dioxide, Electronvolt
Document Summary
Two 8 1/2" x 11" sheet of notes, and scientific pocket. Make sure the exam paper has l" pages. Permittivity of free space, 80 = 8. 85 x 10-12 flm. Permeability of free space, jlo = 1. 26 x 10-6 him. Speed of light in vacuum, c = 2. 998 x 108 mls. Electron charge, e = 1. 6 x 10-19 c. Free electron mass, ida = 9. 1 x 10-31 kg. Electron volt, 1 ev = 1. 6 x 10-19 1. Thermal voltage, kt/q = 0. 0258 v (at 300k) Relative dielectric constant of silicon, k, = 11. 8. Relative dielectric constant of silicon dioxide, k, = 3. 9. Electrons: mn* = 1. 18 ida; holes: mp* = 0. 81 ida. I silicon band gap at 300k, eg= 1. 12 ev. 1: thin film deposition (25 points) a. In the ee143 lab, we use a thermal evaporator the aluminum thin film.
