English Abstract

This thesis discusses the effect of Oxygen, Hydrogen and Nitrous Oxide gases on the electric conductance of Sb-doped ZnO micro-wires.

The micro-wires have a ZnO core and a Sbrich ZnO shell.

The resistance of these wires is quite sensitive to light, temperature and gas environment.

The three parameters seem to affect the conductance of the micro-wire through the same mechanism This electric conductance of ZnO:Sb microwires has a rich behavior that can be utilized in sensing applications because it is sensitive to different kinds of gases.

The latter allows the use of these wires as gas sensors.

This thesis will focus on studying the gas-sensing properties of ZnO:Sb towards H2, O2 and N2O gases as well as the structure of these Sb doped ZnO micro-wires.

The conduction mechanism depends on simple potential divider circuit connected to a (My DAQ).

The DAQ is connected to a LabVIEW program to measure the voltage of the sample and calculate its resistance using a simple equation.

DAQ is also used to measure the temperature on a second channel.

To provide Nitrous gas we get it from a jar with a regulator.

Hydrogen and Oxygen gases were performed by electrolysis of water.

Then we used thin tubes to provide these gases to the sample.
