A)Why is the electrical resistivity of a thin film metal higherthan its bulk value? Choose one.
- a) It experiences excessive surface oxidation - b) It has alower work function - c) Dimensions of the film are comparable tothe mean free path
- d) a and b - e) b and c - f) a and b and c
B) Describe how electrical conduction occurs in a lithiumpolymer electrode?
C) Describe thermal conduction in metals and how it differs fromthermal conduction in an insulator. d) What is drift mobility? Ifwe have conduction by ion diffusion in an insulator, is the driftmobility large or small compared to that of a metal? Why?
D) What is drift mobility? If we have electrical conduction byion diffusion in an insulator or polymeric system, is the driftmobility large or small compared to that of a metal? Why?
