5-3-3 System Benefits of High-Power High-Temperature SiC Devices Uncooled operation of high-temperature and high-power SiC electronics would enable revolutionary improvements to aerospace systems. Replacement of hydraulic controls and auxiliary power units with distributed “smart” electromechanical controls capable of harsh ambient operation will enable substantial jet-aircraft weight savings, reduced [...]
Most SiC electronic devices are not fabricated directly in sublimation-grown wafers, but are instead fabricated in much higher quality epitaxial SiC layers that are grown on top of the initial sublimation grown wafer. Well-grown SiC epilayers have superior electrical properties and are more controllable [...]
5-7-1 Future Tied to Material Issues The previous sections of this chapter have already highlighted major known technical obstacles and immaturities that are largely responsible for hindered SiC device capability. In the most general terms, these obstacles boil down to a handful of key fundamental [...]
5-6-4-1-1 SiC Schottky Power Rectifiers. 4H-SiC power Schottky diodes (with rated blocking voltages up to 1200 V and rated on-state currents up to 20 A as of this writing) are now commercially available . The basic structure of these unipolar diodes is a patterned metal [...]
In optics the refractive index (or index of refraction) n of a substance (optical medium) is a number that describes how light, or any other radiation, propagates through that medium. Refractive index is the basic property of optical crystals, and it is an important parameter [...]
2-16.Pits Individual distinguishable surface anomalies, which appears as a depression in the wafer surface with a lengthto-width ratio less than 5 to 1, and visible under high intensity illumination.
