Abstract
Abstract The dielectric analysis of nanostructured layers of semiconductor materials is important for understanding the characteristics and design of nanocomposites with the prospect of their further application in solar cells and piezoelectric transducers, as well as catalytic particles and sensors in determining the molecular composition of gases. The impedance spectroscopy of a solid makes it possible to characterize various contributions to the resistive and capacitive properties of an electronically inhomogeneous condensed matter and to characterize them separately. In this paper, we study the impedance spectra for nanostructured ZnO layers synthesized by the hydrothermal method on a chip based on Al2O3 with presprayed interdigital gold electrodes, and the dependence of the impedance spectra on the measurement temperature and the concentration of the supplied gas is studied.
