Research Areas

In-situ Physics-of-Failure Analysis: Argonne researchers are leveraging Argonne’s Advanced Photon Source’s (APS) x-ray high-speed imaging (HSI) capability for in-situ physics-of-failure analysis for high power high frequency wide bandgap (WBG) power devices and aerospace component manufacturers. Argonne has built a capability at the APS HSI beamline (32-ID) for testing and performing in-situ physics-of-failure analysis of WBG power devices and components during accelerated stressing and high-speed switching.

Hardness Testing of Power Devices in Extreme Harsh Environments: This research focuses on demonstrating reliability testing of 600 V-1700 V GaN and SiC WBG power devices in high neutron radiation environments and high temperatures (350oC-800oC) at a highly accelerated rate and performing in-situ observation of electrical and thermal properties. Argonne has built the capability to perform extreme condition reliability test in order to facilitate improved? advanced manufacturing of WBG devices for extreme harsh environment application through aerospace and defense industry partners.

Benchmarking WBG Power Devices: The research focuses on benchmarking WBG SiC power devices through accelerated reliability testing. We have developed a thermal aging and bias temperature instability platform. In order to analyze static electrical properties, we have developed statistics and machine learning based on GUI interface.
