High Energy Density Dielectrics for Pulsed Power Applications
Abstract
This report was developed under a SBIR contract. Aluminum oxynitride (AlON) capacitors exhibit several promising characteristics for high energy density capacitor applications in extreme environments. Dielectric constants in the range of 9 and dielectric strength in excess of 650 V/micrometer have been demonstrated in our SBIR Phase II program, resulting in material energy densities greater than 14 J/cc. The dielectric properties remain stable from cryogenic temperatures of -200 deg C to temperatures above 400 deg C. Stacked capacitor devices have been developed and packaged. The high energy density and wide temperature stability make AlON an attractive candidate for many military, space and commercial applications.
