Abstract Details

2017, Master of Science, Miami University, Physics.
The electric conductance of ZnO:Sb micro/nanowires has a rich behavior that can be utilized in sensing applications. This electric conductance readily depends on the ambient temperature, light and the abundance of oxygen around the wire. Through a systematic study we show the effects of light illumination, temperature variation, and oxygen gas flow on the persistent photoconductance of ZnO:Sb micro and nanowires for the development of reliable and stable oxygen gas sensors. The three parameters impact the resistance through the same mechanism of oxygen adsorption and desorption from the surface of ZnO:Sb wire, thus it is important to choose the right temperature and light illumination for efficient and reliable gas sensing.
