Abstract

A solid-state C O₂ sensor device using a metal-insulator-silicon carbide (MISiC) capacitor combined with a Li₂ C O₃ -BaC O₃ auxiliary layer was fabricated and tested for its basic sensing properties. The MISiC-based C O₂ sensor attached with the carbonate showed typical capacitance-voltage (C-V) properties in air at 400°C, and the sensor device responded well to changes in C O₂ concentration in air at 400°C. The sensor signals were directly proportional to the logarithm of C O₂ concentration. The results suggested that an electrochemical reaction of C O₂ occurred at the interface between the carbonate layer and the electrode, causing the applied voltage to shift in response to C O₂.
