Special Issue Information

Dear Colleagues,

The prodigious development of deposition techniques for thin films of regular or innovative materials has made it possible to cover many fields of application. These applications can be considered according to their broad field of implementation (environment, transportation, security, health, etc.). They can also be envisaged according to requirement criteria such as temperature behavior, compatibility with the atmospheric conditions (humidity, particles, wind currents, etc.). A third field of properties concerns the nature of the material to be deposited, and the nature of the substrate and its physical properties (roughness, mechanical resistance, temperature resistance) or physicochemical properties (reactivity, vapor pressure). This review is more specifically devoted to fields related to optoelectronics and microelectronics. These very points of view will be oriented according to the criteria set out above, while understanding the functionality of films. This will include materials entering sensing devices of all types, or materials entering information processing circuitry (either optical or electronic), or finally materials used for information transfer (e.g., lines or waveguides). The review will also welcome contributions related to the fabrication of films (by chemical or physical means), as well as their various characterizations (morphology, structural properties, electrical or optical properties, etc.).

A thin film sensor based on tetragonal SnO2 nanoparticles was fabricated by combining the sol–gel method and a dip-coating technique on a cylindrical glass substrate. The sensing material was produced through a cycling annealing process at 400 and 600 °C, using tin chloride (IV) pentahydrate as a precursor in polyethylene glycol (PEG) solution as a surfactant. Materials were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD), revealing tetragonal phase formation with no impurities. The sensor′s assembly was done with low-cost materials such as Cu electrodes, Cu-Ni tube pins, and glass-reinforced epoxy laminate as the base material. For signal variation, an adequate voltage divider circuit was used to detect ethanol′s presence on the surface of the sensor. The fabricated sensor response to gaseous ethanol at its operating temperature at ambient pressure is comparable to that of a commercial sensor, with the advantage of detecting ethanol at lower temperatures. The sensor response (S = Ra/Rg) to 40 ppm of ethanol at 120 °C was 7.21. A reported mathematical model was used to fit the data with good results. Full article
