Graphene for Room Temperature Gas Sensors [BPN772]
As air pollution from industrial and automobile emission becomes more and more severe, the personalized, integrated
gas sensor is desirable for everyone to monitor everyday's air quality as well as their personal health condition. Such sensor
should have the desirable features like energy efficient,miniature size, accurate response (down to ppm level), flexibility and
selectivity. Traditional 3D semiconductor based gas sensor works in the temperature range of 300 to 400 oC, which requires
large amount of energy to power the heater. We here propose using graphene based field effect transistor to detect and
distinguish gas in both concentration and category concurrently by measuring its electrical properties at room temperature.
