Measurements of the ultraviolet emission spectrum emitted from a lean burn premixed natural gas flame were taken over a range of flame temperatures using a fiber-optic/CCD spectrometer. Combustion temperatures were determined by two methods: by measu

Results of a 1200V 4H-SiC vertical DMOSFET based on ion implanted n+ source and pwell regions are reported. The implanted regions are activated by way of a high temperature anneal (1675°C for 30 min) during which the SiC surface is protected by a la

A dual silicon carbide photodiode chip was developed to determine the temperature of a natural gas combustion flame. The concept uses the change in shape of the 260-350 nm OH band with temperature. One half of the chip was covered with a long-pass mu

Using plan-view transmission electron microscopy (TEM), we have identified stacking faults (SFs) in 4H-SiC PiN diodes subjected to both light and heavy electrical bias. Our observations suggest that the widely expanded SFs seen after heavy bias are f

Stacking-fault growth in SiC PiN diodes has been examined using light-emission imaging and stressing at 80 A/cm2 and 160 A/cm2. Dark areas in the emission develop because of stacking faults and the current capability of the diode drops. More detailed
