The Fabrication And Characterization Of ZnO Gas Sensors: The main objective of this monograph is the application of Cr doped ZnO thin film for gas sensors applications

The sensors and sensors arrays are also used in medical applications, automotive and process control. In general, sensors provide an interface between the electronic equipment and the physical world typically by converting non electrical of physical or chemical quantities into electrical signals. Recently, gas sensors based on the semiconducting metal-oxides (they also are known as resistive or chemoresistive sensors) such as tin dioxide, zinc oxide and tungsten trioxide were found to be very useful for detecting the toxic, harmful and hydrocarbons gases The main objective of this monograph is the application of Cr doped ZnO thin film for gas sensors applications.
