We studied the ionic/electronic transport and resistance degradation behavior of dielectric oxides by solving the electrochemical transport equations. Here, we took into account the non-periodical boundary conditions for the transport equations using the Chebyshev collocation algorithm. A sandwiched NijSrTiO 3 jNi capacitor is considered as an example under the condition of 1.0 V, 1.0 lm thickn...

We investigate the effect of a small leakage current through the gate insulator on the stability of organic single-crystal field-effect transistors sFETsd. We find that, irrespective of the specific organic molecule and dielectric used, leakage current flowing through the gate insulator results in an irreversible degradation of the single-crystal FET performance. This degradation occurs even wh...

although in recent two decades, the concept of dielectric barrier discharges (dbds) have been developed in ozone production well, air pollution control, plasma screens and control of chemical, and biological and medical processes, employment of this concept for high voltage applications to improve insulation performance as an alternative to the pressurized gas-insulated systems (gis) utilizing ...

It has been clear for a number of years that increasing transistor gate leakage with device scaling would ultimately necessitate an alternative to traditional SiON dielectrics with polysilicon gates. Material systems providing higher dielectric constants, and therefore allowing physically thicker dielectrics, have been the object of extensive research. Such high-k dielectrics, when combined wit...

Development of the power grid towards a more reliable and smarter system requires frequent on-line monitoring of the power components. Power transformers and their bushings are particularly important components in a power transmission system and their insulation degradation may lead to catastrophic failures. Time consuming and costly replacement of these components raise the importance of their...

We demonstrate significant improvement of the radiation immunity integrated circuits based on silicon bipolar transistors. Strong decrease current gain degradation and yield after high-energy gamma irradiation are both shown. This was achieved by development efficient hydrogenation process for bulk surface dielectric layer using electron cyclotron resonance (ECR) plasma, as well implementation ...

nanocomposite materials, including noble metal nanoparticles embedded in a dielectric host medium, are interesting because of their optical properties linked to surface plasmon resonance phenomena. for studding of nonlinear optical properties and/or energy transfer process, these materials may be excited by ultrashort pulse laser with a temporal width varying from some femtoseconds to some hund...
