Space charge accumulation characteristics in ethylene-tetrafluoroethylene copolymer under DC high stress

摘要

Irradiating an electron beam to the ETFE, it is thought that electron-hole pairs are generated inside the sample. However, there is no reported cases about this problem. Therefore, by using a blocking layer to block the charge injection from the outside, an inside of an irradiated sample electron-hole pairs were investigated whether it is produced in the DC stress.
