| Abstract: | The microscopic mechanism of non-linear effect is studied using timedomain paramete4s.The macroscopic property of ZnO in varistor is determinedby four different components of the microscopic structures.The leakage curre-nt is determined by the two barrier layers connected in series and the non-lin-ear index of conductivity is determined by grains and intergranular layer.Thefree relaxation time of space charges in barrier-layers is as long as 200 s. |
