Research Interests

Developing materials that retain their properties despite being subjected to harsh conditions is a key challenge throughout materials science. The lack of understanding in this domain has technological impact, including for nanoelectromechanical (NEM) contact switches, which have been identified by the International Technology Roadmap for Semiconductors as a possible “beyond CMOS” technology. Despite exhibiting a significantly decreased power consumption compared to currently used solid-state switches, NEM contact switches face a barrier to commercialization due to reliability issues, which are related to contact interface related failure mechanisms.

My research is motivated by the need for novel NEM switch contact materials that are highly conductive, mechanically robust, minimally adhesive, chemically inert, and amenable to CMOS fabrication processes. The aim of my work is the development and characterization of potential next-generation NEM contact materials that may facilitate the commercialization of NEM contact switch technology. Characterization methods I am using include angle-resolved and environmental X-ray photoelectron spectroscopy (AR-XPS, E-XPS) , ultra-high vacuum atomic force microscopy (UHV AFM), nano-indentation and scanning and transmission electron microscopy (SEM, TEM).
