“…Thanks to their larger bandgap, materials based on Gallium Nitride (GaN) can more easily absorb photons associated to low wavelengths independently from its thickness and then achieve high responsivities below 400 nm (Chang et al, 2008;Biyikli et al, 2005;Monroy et al, 2001). Other frequently used technology is the silicon carbide (SiC) that has proven its interest by the past (Brown et al, 1998;Fang et al, 1992).…”

Clean, efficient energy production, such as the gasification of coal (syngas), requires physical and chemical sensors for exhaust gas monitoring as well as real-time control of the combustion process. Following a description of syngas production from coal, we outline the sensing needs for this high temperature, chemically corrosive gas stream.The performance of devices based on the wide-bandgap semiconductor SiC, for monitoring gas composition, flame dynamics and temperature, as well as combustor structural integrity in this extreme environment are reviewed. We have developed a Pt-SiO 2 -SiC micro-device with a dense Pt catalytic sensing film, for fast (<1s) detection of hydrogen containing species at 630 °C. Our SiC sensor can monitor the hydrogen concentration in a 350 °C simulated syngas ambient containing the common interferants CO 2 , CH 4 and CO. Exposure to H 2 S (~1000 ppm) and water vapor does not degrade the sensor performance.
