A theoretical investigation of the power-law response of metal oxide semiconductor gas sensors Ι: Schottky barrier control

This study presents a theoretical investigation of the power-law response of metal oxide semiconductor gas sensors which is characterized by a linear dependence of the sensor resistance on gas pressure or concentration in double-logarithmic plots. The connection of sensor resistance with the gas partial pressure is realized by a set of differential equations, which describe the receptor and transducer functions of metal oxide semiconductor...
