摘要：
In this paper, a theoretical study of the single electron molecular transistor (MSET) as a gas sensor has been presented. Using the Quantum ATK simulator, density functional theory coupled with the green nonequilibrium function was applied to calculate the carrier transport properties and adsorption effects on the pentacene-based single electron transistor (C22H14-MSET). The simulation results show good sensitivity to detect ammonia equal to 58% at a concentration of 200 ppb with a detection limit of 40 ppb. The sensitivity as a function of concentration shows a linear evolution which proves that MSET sensor has a good sensitivity. The present results make the MSET sensor is a very promising candidate to detect a toxic gas at low concentration and to fabricate a small size gas sensor.
