Presented at ICALEO 2009
Laser doping is used to modify the reflectivity and refractive index of embedded regions in wide bandgap semiconductors for selective detection of gaseous chemical species. Each of the four quadrants of a 1 cm x 1 cm x 300 microns silicon carbide (SiC) sensor are laser doped with a different element; gallium, aluminum, scandium and phosphorus, respectively; to create energy levels that selectively absorb photon emissio...$28.00
