Unravelling the anomalous dielectric permittivity of nanoconfined electrolyte solutions.
The dielectric properties of sodium chloride solutions confined in a hydrophilic nanocavity were investigated by means of molecular dynamics simulations. Unlike what is observed in the bulk phase, three dielectric regimes were evidenced, namely an anomalous increase in the dielectric permittivity at low concentrations (with respect to confined pure water), a dielectric plateau at intermediate c...
متن کاملThickness Dependent Dielectric Strength of a Low-permittivity Dielectric Film
The dielectric strength of a promising interlevel low relative permittivity dielectric is investigated for various film thicknesses and temperatures by using I-V measurements with metalinsulator-semiconductor (MIS) structures. It is found that the dielectric breakdown mechanism also depends on thickness. For relatively thick films (thickness >500 nm), the dielectric breakdown is electromechanic...
متن کاملAn ionic concentration and size dependent dielectric permittivity Poisson-Boltzmann model for biomolecular solvation studies.
By considering the influence of volume exclusion on the solvent dielectric, a variable dielectric Poisson-Boltzmann (VDPB) model is explored for molecular solvation studies by using a dielectric as an explicit function of ionic sizes and concentrations. A finite element method is adopted and an iterative strategy is introduced to numerically solve the VDPB equation. According to our computation...
متن کاملA nanocapacitor with giant dielectric permittivity
A nanocapacitor with ultra high capacitance (718 ± 0.2 pF) has been fabricated using electro-deposited Au nanowires manipulated between two Au microelectrodes by the dielectrophoresis technique. A high dc resistance value (∼100 M ) and nonlinear current–voltage characteristics indicate the formation of a dielectric interface between the nanowires. From frequency dependent conductivity, it is se...
متن کاملTime Domain Reflectometry: Temperature- dependent Measurements of Soil Dielectric Permittivity
The purpose of this study is to determine the temperature influence on the soil bulk dielectric permittivity, ε b, calculated from the measurement of the electromagnetic wave velocity of propagation along the parallel waveguide in a TDR probe, i.e. a probe working in Time Domain Reflectometry technique. The experimental evidence shows that the existing models do not completely describe the temp...
