Dr. Sitaramanís research is in the areas of nano-scale and micro-scale structure fabrication, characterization, physics-based modeling and reliable design intended for various applications: aerospace and defense, automotive, computers and telecommunications, portable electronics, and medical. In particular, his research is developing arrays of nano-scale and micro-scale free-standing structures that can be used as bio-assays for disease diagnosis and as compliant off-chip interconnects. The bio-conjugated nano-cantilever (25-100 nm thick, 50-250 nm wide, and 300-1000 nm long) arrays can be used for detecting tumor-associated serum antigens at low levels of concentration far exceeding what is possible today through other available techniques. Such an ability to detect extremely low levels of circulatory antigen concentration and the ability to periodically monitor the increase in the antigen concentration will facilitate early detection of tumor as well as intervention and cancer patient treatment management. The off-chip interconnects, on the other hand, are wafer-level, scalable, compliant, and reworkable and are intended for 45-nm and sub-45-nm ICs.
Dr. Sitaramanís group is also developing innovative fixture-less superlayer based decohesion tests for measuring the mode-mixity-dependent interfacial fracture toughness for thin films and can be potentially used for films with a thickness ranging from 5 nm to 1-2 mm. Mechanical characterization of deposited nano thin films with a thickness of about 600 nm is also being done using nano-indentation.
