Clayey soils are the most common material used for water sealing and undertake an important role in controlling landfill-related pollution. Organic liquids can adversely affect the effectiveness of clay liners by drastically increasing their hydraulic conductivity. The aim of this study is to investigate and compare the permeability in two types of clay with different plasticity, exposed to the...

Major sterilization mechanisms are related to atoms and radicals, charged particles, excited molecules, ozone, and UV radiation. The ROS (Reactive Oxygen Species) are well known as evildoers. These species are easily created in ambient air and water and they live long enough to reach the cell and attack the organic matter. Test molecules conversion in dry and wet air is studied using Dielectric...

CP measurements show that PBTI stress induced interface trap area density ΔNit in InGaAs/Al2O3 n-MOSFET is very small and has power law time evolution At in the stress phase, and is partially recovered in the recovery phase. However the DC Is-Vg measurements show large degradations of negative ΔVg and sub-threshold swing S in the sub-threshold region and are recovered in the recovery phase, als...

Recent HK reliability studies reflect increasingly complex and diverse gate stack structures fabricated to meet device scaling requirements. Essential progress towards achieving low values of the threshold voltage was made through the introduction of the metal oxide capping layers in gate stacks that, in turn, instigated a number of reliability studies of these systems. Employing fast measureme...

Plasma-induced etching of dielectric thin films is widely used in ~ntegratedcircuit preparation technology. It normally involves the interaction of gas discharge species with a thin-film surface in order to produce volat~le reaction products. The ultimate goal is to etch through a frlm in a spatially selective manner and to thereby generate a desired pattern. This process also occurs unintentio...

In this work, we investigated the stability of Molybdate-Phosphonic Acid (MPA) complex by density functionaltheory (DFT) computations in six solvents with the dielectric constant ranging from 1.92 to 10.36. The methodsare used for calculations are B3LYP and B3PW9 I that have been studied in two series of basis sets: D95nand6-31+G (d,p) for hydrogen and oxygen atoms; LANL2DZ for Mo and Phosphoru...

The dielectric susceptibility and dielectric tunability of the temperature-graded BaTiO3 thin films are investigated by using a modified transverse Ising model, taking the four-spin interaction and quantum fluctuation into account. There is a broad and smooth peak of the dielectric susceptibility at low temperature except for the sharp dielectric peak corresponding to the phase-transition tempe...
