We are focused on reliability and sustainability challenges in electronic, optoelectronic, and heterogeneously integrated devices. Our work seeks to understand degradation mechanisms in devices and accordingly engineer materials/defects. Researchers in the EMRS Laboratory are developing sustainable and stable materials for renewable energy and electronics packaging applications. The underlying theme of our research is to enable innovation and design of high-performance materials and devices by exploiting the fundamental connection between material structure/defects and resulting electro-thermo-chemo-mechanical device degradation mechanisms. We follow a unified approach of device and materials modeling, fabrication, testing and characterization.
