The current density J and electric field E in the insulator can be related as follows:
The calculated barrier heights are 26.97, 21.98 and 19.10. The results don't have the physical meaning.

[Q6] and [Q7] Plot Fowler-Bordheim(FN) graph on log-lin scale and calculate the barrier height
The graph of FN graph is shown as following:
The whole graph looks strange for the break down range. Therefore, the experimenter cut only the range of near zero data. The data is almost right refer to the material the supervisor gives us.
The current density J and electric field E in the insulator can be related as follows:
So that it is important to convert the Ln value of J/(E^2) and the slope is a function of barrier height.
The calculated barrier heights are 26.97, 21.98 and 19.10. The results don't have the physical meaning.

ReplyDeleteThe blown film thickness process is the method by which the vast majority of all polythene products are manufactured.
The film thickness is air cooled to set the film dimensions.
