AModel of Temperature Dependence of the Amplitude-Frequency Response of a Molecular Electronic Sensor Based on a Water-Alcohol Solvent

The paper presents the results of modeling and their verification based on numerous experimental studies of the temperature dependences of the amplitude-frequency characteristics of molecular-electronic sensors as exemplified in a linear displacement sensor. Data on the temperature dependence of the amplitude-frequency characteristic and background currents for a water-alcohol based electrolyte with the addition of low concentrations of potassium iodide have been accumulated and systematized. Various types of conversion nodes have been studied, differing in the conversion area, the number and density of electrode grids. While processing the results, refined models of temperature dependences have been formed, analytical approximating curves have been selected for each family of characteristics, and the activation energies of viscosity and diffusion have been calculated for various physical mechanisms that manifest themselves in the observed experimental patterns.
