Space charge accumulation on multilayer graphene/epoxy nanocomposites
2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2013Nanocomposite materials are nowadays widely studied. It is often desired, by the addition of nanoparticles in an insulating matrix, to improve electrical and thermal properties. However, few types of nanoparticles enable improvement of combined electrical and thermal properties.

Approximations for accumulation and inversion space-charge layers in semiconductors
Solid-State Electronics, 1968Abstract The solution of Poisson's equation for heavily accumulated or inverted space-charge regions in semiconductors is discussed. Closed form solutions are obtained for such regions. These solutions make it possible to obtain good approximations to potential and carrier density variations with distance in semiconductor surface space-charge layers.

Study of the factors that suppress space charge accumulation in LDPE nanocomposites
IEEE Transactions on Dielectrics and Electrical Insulation, 2014Two mechanisms have been proposed to explain the suppression of space charge in polyethylene by the addition of nano-fillers, i.e. an interface change that reduces charge injection and a bulk modification that affects charge migration and recombination.

Space charge accumulation properties in XLPE with Carbon nano-filler
2012 IEEE International Conference on Condition Monitoring and Diagnosis, 2012The space charge accumulation properties under dc high stress at various temperatures were investigated in cross-linked polyethylene (XLPE) and XLPE/Carbon composite. We have reported, earlier, that low density polyethylene (LDPE) including inorganic nano-size filler shows a good performance without accumulation of space charge even under very high dc ...

The temperature dependence of space charge accumulation in cross-linked polyethylene
Journal of Thermal Analysis, 1997Abstract This paper presents the results of laser-induced-pressure-pulse (LIPP) measurements of space charge accumulation in 0.5 mm thick planar XLPE samples with aluminium electrodes, over the temperature range 30–90°C. The applied field strength was 10 kV mm−1.

Space Charge Accumulation and Micro-Structure of Cross-linked Polyethylene
Japanese Journal of Applied Physics, 2004In this paper, laser induced pressure pulse (LIPP) method and electrostatic force microscopy (EFM) method are utilized to investigate the distribution of space charge in cross-linked polyethylene (XLPE), and the action on the groups of XLPE by the accumulative charge are investigated by infrared spectroscopy (IR) method.

The Influence of corona discharge on space charge accumulation in polyimide film
2013 Annual Report Conference on Electrical Insulation and Dielectric Phenomena, 2013The space charge accumulation processes in polyimide film under corona discharge from spherical electrode are observed using improved open-electrode type PEA (pulsed electro-acoustic) measurement system. To reduce the electric power consumption, the efficient-energy motor is required to be developed.

Space charge accumulation and conductivity of crosslinking byproducts soaked LDPE
2010 Annual Report Conference on Electrical Insulation and Dielectic Phenomena, 2010The crosslinking byproducts have significant influences on the electrical performance of the Crosslinked Polyethylene (XLPE). In this paper, the effects of acetophenone, α-methylstyrene and cumyl alcohol on space charge formation and conductivity values have been investigated. The space charge measurement was conducted using Pulse Electroacoustic (PEA)
