Using a MISiCFET device as a cold start sensor

Amperometric hydrocarbon sensor using La(Sr)Ga(Fe)O3 solid electrolyte for monitoring in exhaust gas

“…There are some reports available on the working conditions under cold start operation [3,4]. At low operating temperature, the selection of sensor material is very crucial for the detection of hydrocarbon.…”

Detection of hydrocarbon species using silicon MOS field-effect transistors operated in a non-stationary temperature-pulse mode

“…Under such hightemperature conditions not only hydrogen but also much more stable hydrocarbon species can be detected. Most of this research was motivated by the interest of applying fieldeffect gas sensors to harsh environment applications such as exhaust gas and flue gas monitoring [14][15][16][17][18][19][20][21][22][23][24].…”

Improved Thermal Stability Observed in Ni-Based Ohmic Contacts to n-Type SiC for High-Temperature Applications

“…[1,2] Metal-insulator-silicon carbide (MISiC) sensors have been developed at the Swedish Sensors Centre (S-SENCE) and continues now at the Functional Nanoscale Materials, FunMat, Centre at Linköping University in Sweden; the sensors can operate in oxidizing ambients for short durations at temperatures up to 700 C. [3] One of the critical limitations to long-term operation of SiC gas sensors at high temperatures, however, is the degradation of the metal-SiC contacts. This problem is associated with metal-SiC reactions to form silicides, carbides, and/or free carbon, and oxidation.…”
