Trapping parameters estimation of fresh and thermally-aged low-density polyethylene by using an improved trapping/detrapping model

Trapping parameters estimation of fresh and thermally-aged low-density polyethylene by using an improved trapping/detrapping model
In the present paper, trapping parameters of normal and thermally aged low-density polyethylene (LDPE) samples were estimated using the improved charge dynamic model. The results show that, after long-term thermal ageing process, the injection barrier of both electrons and holes is lowered, the overall trap depth is shallower and electron trap density becomes much greater. The latter may indicate that electrons are more sensitive to ageing than those of holes.

Abstract

In the present paper, trapping parameters of normal and thermally aged low-density polyethylene (LDPE) samples were estimated using the improved charge dynamic model. The results show that, after long-term thermal ageing process, the injection barrier of both electrons and holes is lowered, the overall trap depth is shallower and electron trap density becomes much greater. The latter may indicate that electrons are more sensitive to ageing than those of holes.
