| Abstract: |
| Abstract: ?? A more comprehensive survey of the research states on the electric conduction mechanism of thick film resis??
tance was presented in this paper, and many kinds of conduction patterns, theory and their defects, for example, uniform
model, uniform channel model and non- tunneling barrier model were introduced too. To the tunneling barrier model,
particular analysis and discussion were carried through, and these theories were utilized to expound the temperature depen??
dence of conductance, electric field dependence of conductance and thermoelectric effect of thick film resistance. |
