Study on (n+n) Type Acetone Gas Sensor

Abstract:

(n+n) structure semiconductor gas sensor based on the compensation-feedback principle is composed of two sensitive materials A and B which are all n-type materials. The results analyzed from a theoretical viewpoint show that the (n+n) combined structure semiconductor gas sensor has higher selectivity, better thermal stability and higher sensitivity than conventional sensors when the materials A and B satisfied certain conditions. Though testing the characteristics of the (n+n) combined structure semiconductor gas sensor, the perfect (n+n) combined structure acetone gas sensor is fabricated, and could be applied to monitor and control leakage of acetone gas.
