Simultaneous measurements of space charge and external current for LDPE films with various densities

Positive charges packet is frozen inside the bulk of a low-density polyethylene(LDPE) ﬁlm after subjecting to 1.5 MV/cm of DC electric ﬁeld. In this paper, simultaneous measurements of space charge dynamics and external current through LDPE are carried out by using a pulsed electroacoustic (PEA) met...
