Modelling of the influence of the layer pollution thickness in high voltage polluted insulators
(1995-12-01)
An experimental model and a mathematical model with the introduction of a ramp in the channel of Obenaus model are presented. The aim is to present a better reproduction of the real layer pollution deposited on the HV ...
Powder Diffraction of Components Subject to Corrosion in Fuse Cutouts with CeramicInsulation
(Trans Tech Publications Ltd, 2008-01-01)
Aiming identification of the components most affected by corrosion under saline environment conditions, we have carried out X-ray diffraction measurements in ceramic and bond materials, all in the powder form. The ceramic ...
Surface modification by metal ion implantation forming metallic nanoparticles in insulating matrix.
(Kusadasi, 2013-09-15)
There is special interest in the incorporation of metallic nanoparticles in a surrounding dielectric matrix for obtaining composites with desirable characteristics such as for surface plasmon resonance, which can be used ...
Impact of gate dielectric material on basic parameters of MO(I)SHEMT devices
(2020-04-01)
In this work, the behavior of MISHEMT devices with different gate materials is analyzed. Two-gate insulator materials (Al2O3 and SiN) were analyzed through the transfer characteristic, threshold voltage, hysteresis and ...
Optical and transport properties of rare-earth trivalent ions located at different sites in sol-gel SnO2
(2010-12-01)
Photoluminescence and photo-excited conductivity data as well as structural analysis are presented for sol-gel SnO2 thin films doped with rare earth ions Eu3+ and Er3+, deposited by sol-gel-dip-coating technique. ...
X-boson Cumulant Approach To The Topological Kondo Insulators
(Institute of Physics Publishing, 2014)
Electrode poling of cellular polypropylene films with short high-voltage pulses
(2002-01-01)
Recently, piezoelectric cellular polypropylene (PP) was proposed as a new type of quasi-ferroelectric. The observed hysteresis of the charge density as a function of the electric field could be explained as field-dependent ...
