The distinguishing characteristic of an insulator is its resistivity. An has a higher resistivity than semiconductor or conductor and high dielectric properties. adjustable property characterized by change in the permittivity under applied electric field, this phenomenon called "dielectric nonlinearity" (dielectric tunability properties). With these properties, new will arise properties ceramic...

We used our previously implemented GW approximation (GWA) based on the all-electron full-potential projector augmented wave (PAW) method to study the optical properties of small, medium and large-band-gap semiconductors: The aim being to study the size of both local-field (LF) and the quasi-particle (QP) corrections to the calculated dielectric function obtained using the local density approxim...

Fluctuations of the dipole moment of a macroscopic dielectric sample are induced by thermal motions. The variance of the sample dipole moment, characterizing the extent of thermal fluctuations, is a decaying function of temperature for many polar liquids. This result is inconsistent with the Nyquist (fluctuation-dissipation) theorem predicting the variance of a macroscopic property to grow line...

hin film characterization is important for the semiconductor industry as it pushes for smaller and faster circuits and devices. Materials with a high dielectric constant are required for improved insulation and reduction of tunneling between layers, and low dielectric materials are needed for interconnects with reduced capacitance [1]. As feature sizes of circuits and devices approach 100 nm an...

In this paper, the influence of floating dummy metalfills on interconnect parasitic is analyzed with the variations of possible factors which can affect the capacitance. Recently proposed chip-level metal-fill modeling, replacing metal-fill layer with effective high-k dielectric, has been reviewed in detail. Using a systematized modeling flow, the property of the effective permittivity in the m...
