Abstract
Device characteristics of a new type of O2 gaseous sensor are presented. These sensors are fabricated in the MIS configuration Pd-SnOx -Si3 N4 -SiO2 -Si-Al with highly resistive SnOx as an oxygen adsorptive element. Partial pressures of O2 below 0.1 torr can be detected at room temperature by these devices. Steady-state and transient behavior are described as a function of O2 partial pressure and temperature. Adsorption and desorption rates and time constants are determined. Activation energy for O2 adsorption in SnOx is found to be 1.6 K cal/ mole.
