Improving reliability of SCB initiators based on Al/Ni multilayer nanofilms

Abstract

This paper exploits an energetic initiator realized by integrating Al/Ni multilayer nanofilms with semiconductor bridge (SCB). The as-deposited nanofilms have been characterized with varied analytical techniques. Results show that distinct nanofilms are sputter deposited in a layered geometry and give a heat of reaction equal to 1134 J/g. The firing tests of the initiators were accomplished using capacitor discharge unit. Results show that the initiators possess several excellent characteristics such as fast ignition time, low power consumption, high output energy and so on. Therefore, Al/Ni multilayer nanofilms are suitable heat source for improving the reliability of SCB initiators.
