Abstract:
With the help of experimental data in low density
polyethylene (LDPE), obtained from pulsed electro-acoustic
method, a significant amount of concentration gradient can be
seen. However, different simulation models of homocharge
accumulation present in the literature, considers only the drift
phenomenon of charge carriers while neglecting the diffusion.
These models envisage the homocharge formation with limited
accuracy. With the help of recently published analytical
equations of space charge and electric field, the individual role
of conduction of charges in bulk, diffusion of charge carriers
and injection from the electrodes are delineated.
