{"Image DocumentName": "Quantum Theory of Electrical Conduction", "Image ImageDescription": "Arnold Sommerfield used correct distribution n(E) at room temperature and found a value for \u03b1 of \u03c02 / 4. With the value TF = 80,000 K for copper, we obtain cV \u2248 0.02R, which is consistent with the experimental value! Quantum theory has proved to be a success. Replace mean speed in Eq (9,37) by Fermi speed uF defined from EF = \u00bd uF2. Conducting electrons are loosely bound to their atoms. these electrons must be at the high energy level. at room temperature the highest energy level is close to the Fermi energy. We should use.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
