Modelling and recreation of Semi Conducting Metal Oxide (SMO) Gas Sensor

Abstract

The work is focused on the design of the semiconducting metal oxide gas sensor. This sensor is used for detection and analysis of different type of gases. These gas sensors are of different shape and size, and each metal oxide is used for detecting different types of gases. No two gas sensors are alike. According to the substrate that is being doped on to the sensor, each sensor detects different gases. We will then design the gas sensor in COMSOL software and simulate it. These gas sensors are highly sensitive and hence effect different factors related to surface reactions such as temperature, humidity, chemical components, and structure of sensing layer.
