Space-charge limited conductionIn this work, a novel mixture of ionic liquid gel polymer electrolyte (ILGPE), containing 1-butyl-3-methylimidazolium bromide, ammonium acetate and poly(vinyl alcohol), with Si@C and SiO2 embedded nanoparticles is fabricated. The resulting CILGPE is deposited onto ...
The effect of weight fraction (1–4%) of NiCl2 dopant on some parameters characterising the space charge limited conduction (SCLC) in polymethylmethacrylate (PMMA) composites was investigated. The studied parameters are the concentrations of traps, trapped and free charge carriers. It was implied ...
Space-charge limited current theory with an exponential distribution of traps is however in extremely good agreement with all of the recorded current–voltage results in the higher applied bias regime (approximately0.7V/d1.6×106Vcm1). This gives a trap densityHtof5(±2)×1017cm3and the product...

An investigation is reported of the conduction mechanism in thin films of polypropylene formed by vacuum evaporation. Space-charge-limited conduction was found to be dominant at 275 K.doi:10.1080/00207218608920898IQBAL, TARIQHOGARTH, C. ATaylor & Francis GroupInternational Journal of Electronics...
The relaxation of a space charge due to trapped electrons in an n + -i-n + hydrogenated amorphous silicon structure has been modelled by Solomon. Here we extend the model by obtaining analytical expressions for the current at the beginning of the relaxation as well as for long times when ...

The present paper reports the measurements on space charge limited conduction in vacuum evaporated amorphous thin films of Ge 22 Se 78 and Ge 22 Se 68 M 10 (M = Cd,In, Pb, and Te). Current, at high fields (~ 10 4 V/cm), could be fitted to the theory of space charge limited co...
