In the paper, mathematical models for determination of resistivity of thin antistatic coatings are presented. The models are combination of the classic four-point method and the method of images. Models 2D and 3D are taken into considerations. In both cases are analyzed the parameters of measuring system and coating layer for example: the relations between the sample size and the distance between...
The paper examines the influence of turbulence and convective processes in the surface layer electrodynamic structure. The electrodynamics model of a non-stationary horizontally-homogeneous surface layer is developed with taking into account the coefficients of turbulence diffusion and convection mixing. It is received, that the convection mixing intensification increases the vertical scale of volume...
Capacitive humidity sensors were fabricated using countersunk interdigitated electrodes coated with amorphous nanostructured TiO2, SiO2, and Al2O3 thin films grown by glancing angle deposition. The capacitive response and response times for each sensor were measured. The sensor utilizing TiO2 exhibited the largest change in capacitance, increasing exponentially from ~ 1 nF to ~ 1muF for an increase...
The purpose of this paper is to describe a technique for characterizing near steady state charge transport in thin film dielectric materials under various well controlled ambient conditions. This is important because failure to achieve perfect insulation limits the performance of several sorts of devices. For example, materials used to separate layers of hybrid circuits become lossy at high ambient...
