Doctoral student Jaesung Lee wins best student paper competition on nanoscale devices

Jaesung Lee, a PhD student in the Department of Electrical Engineering & Computer Science (EECS), won the Best Student Paper Competition at the 2014 IEEE International Frequency Control Symposium (IEEE IFCS 2014), for presenting his paper, “Atomically-Thin MoS2 Resonators for Pressure Sensing.” Philip Feng, assistant professor of electrical engineering and computer science and T. Keith Glennan Fellow, mentors Lee.

In the paper, Lee and Feng reported an experimental investigation of a new type of nanoscale devices that are exceptionally responsive to small pressure variations and yet can tolerate pressure changes over wide ranges.

With further engineering, these devices and the optical techniques used can be integrated into flexible optical fibers, which may lead to ultrasensitive pressure monitoring in harsh environments such as inside human body and in drilling or mining down holes, where electrical wiring of sensors is often undesirable.

In previously published research, Lee, Feng and their colleagues demonstrated the world’s first MoS2 2D nanoresonators, also featured by NanotechWeb and the Royal Society’s ChemistryWorld.

Upon winning the student paper competition, Lee said, “I am honored and very fortunate.  I have learned a lot from this conference and enjoyed sharing research ideas with the IFCS community.  It’s a very encouraging news for me that people think our experiments on the new 2D devices are interesting and promising.”

IEEE IFCS is the annual international forum on frequency control, time standards, and sensing technologies, including a wide range of emerging devices such as MEMS and NEMS resonators, integrated electrical oscillators and clocks, microwave frequency standards, and chip-scale atomic clocks.

This work has been supported by Case School of Engineering and the National Academy of Engineering’s Grainger Foundation Frontiers of Engineering (FOE) Award.  The IEEE Ultrasonics, Ferroelectrics and Frequency Control (UFFC) Society provided part of Jaesung’s travel support for student paper competition finalists.
