Title Proper : Investigation into the Hydrogen Gas Sensing Mechanism of 3C-SiC Resistive Gas Sensors
Note : This document is digital این مدرک بصورت الکترونیکی می باشد
Abstract : The hydrogen (H2) gas sensing mechanism driving 3C-SiC resistive gas sensors isinvestigated in this work in which two hypotheses are proposed. One hypothesis involvesthe surface adsorption of H2 on the sensor surface with the adsorbed moleculesinfluencing the flow of current in a resistive gas sensor, termed the surface adsorptiondetection mechanism. The second hypothesis includes the transfer of heat from thesensor to the gas, producing a change in the temperature of the device when the heattransfer characteristics of the gas change, termed the thermal detection mechanism. Theheat transfer characteristics of the gas are dependent on the thermal conductivity of thegas, a property which is a strong function of gas composition. Thus, the thermaldetection mechanism mainly detects changes in the thermal conductivity of a gas or gasmixture..
