Key Points

  • The study aims to explore how oxygen chemisorption impacts the electrical and optical properties of nanocrystalline SnO2 and ZnO films.
  • Measured thermally stimulated conductivity kinetics at varying temperatures.
  • Analyzed thermoelectric power and photoconductivity spectra.
  • Conducted reflection and transmission measurements from 300 to 800 K.
  • Used a generalized equation to interpret the adsorption of oxygen species.
  • Identified extrema in the temperature dependences of conductivity and optical properties.
  • Observed peaks in gas sensitivity aligning with maxima in oxygen chemisorption.
  • Provided explanations for the origins of these extrema through chemisorption dynamics.

Abstract

The influence of oxygen chemisorption on the electrical and optical properties of gas-sensitive nanocrystalline SnO2 and ZnO films is studied by measuring the temperature dependences of thermally stimulated conductivity kinetics, thermoelectric power, photoconductivity spectra, reflection, and transmission in the temperature range of 300–800 K. Extrema are observed in the obtained temperature dependences, and their origin is explained by the chemisorption of various oxygen species using a generalized equation of equilibrium activated adsorption. The regions of maximum gas sensitivity coincide in temperature with the peaks of oxygen chemisorption.
