The electrodes of semiconductor gas sensors are important in characterizing sensors based on their sensitivity, selectivity, reversibility, response time, and long-term stability. The types and materials of electrodes used for semiconductor gas sensors are analyzed. In addition, the effect of interfacial zones and surface states of electrode-semiconductor interfaces on their characteristics is ...

_ This paper presents some of the techniques used to introduce simulation of semiconductor fabrication processes to undergraduate electrical engineering students at the American University of Sharjah. Students use Silvaco Athena process simulator and Atlas device simulator to perform experiments on semiconductor fabrication processes. Simulation results are compared with the theoretically expec...
