Study of Single Element Chemical Sensor Devices based on Semiconducting Metal Oxide Materials


A detailed study of the gas sensor response of sensor devices based on 1D nanostructures is proposed in this project. For this, different stoichiometries of tin oxide (SnO2, SnO and Sn3O4) nanobelts, synthesized by the carbothermal reduction method, will be used as sensor elements. The materials will be characterized by X-ray diffraction (XRD), high-resolution transmission (TEM) and scanning (SEM) electron microscopy, atomic force microscopy (AFM) and X-ray and ultraviolet photoelectron spectroscopy (XPS and UPS). Sputtering and dual-beam microscopy (focused ion beam, FIB) will be used to assemble the sensor devices composed only of (a) an n-type semiconductor nanostructure (b) a p-type semiconductor nanostructure and (c) two crossed semiconductor nanostructures (one n-type and one p-type) in order to create p-n junctions. Gas sensor response of the sensor will be analyzed after exposure to low concentrations (in ppm range) of oxidizing and reducing gases at different operating temperatures. The major challenge of this work will be to build and characterize a "3-in-1" gas sensor device with a special design that allows simultaneous study of the sensor properties of each channel (p-channel, n-channel and p-n-channel) independently in a single device. The focus will be to understand how to optimize gas sensor performance that could enable the development of unique low power and high-performance gas sensor devices with great potential for future technological applications within the nanotechnology field.
