Applied and Engineering Physics senior undergraduate, Jovana Andrejevic, has been awarded a prestigious NSF Graduate Research Fellowship. Jovana has been working in the Clancy group in CBE for the past two years, creating a new approach to modeling chemically reactive species for quantum dot nucleation and growth, mentored by Clancy PhD student, James Stevenson. Jovana’s work resulted in a first-author publication in J. Chem. Theor. & Computation in 2016. She is active at Cornell as a physics tutor, as an outreach coordinator for SWE, and manages part of Cornell’s Community Center program. She is the winner of several Cornell awards, including the Rhodes Scholarship and a Cornell Engineering Alumni Association award. The NSF graduate fellowship is awarded to just ~2,000 outstanding students out of ~17,000 applicants across all STEM fields. Jovana will be attending graduate school in Fall 2016.
Clancy group’s second-year PhD student, Mardochee Reveil, and his work was featured on Cornell’s research page; see feature page. He describes his computational studies on III-V materials that could be faster than traditional silicon devices and with better heat transport characteristics. These new materials could keep us on the Moore’s law fast-track.

Mardochee Reveil from Paulette Clancy’s research group at Cornell won the Best Poster award at the 2015 annual meeting of Cornell’s Nanofabrication Facility. His poster, “Characterizing the Behavior of Van der Pauw Devices under non-Ideal Conditions,” featured his innovative computational work to understand how the performance of van der Pauw devices is affected by changes in the size and shape of the contact as the contact dimensions are decreased. These devices are a commonly used way to determine thin film sheet resistances. Reveil has a Masters degree from Syracuse University and is currently a PhD candidate in the School of Chemical and Biomolecular Engineering at Cornell. He works closely with our experimental partner group, led by Prof. Michael O. Thompson (Mat. Sci.& Engr.), focusing on understanding dopant activation and diffusion in InGaAs.
James Stevenson (Cornell, Chemical Engineering PhD candidate) presented a talk at the Keck Institute for Space Sciences (KISS) at CalTech this summer based on work published in 2015 with his advisor, Paulette Clancy, and astronomer Jonathan Lunine in Science Advances. His work discussed the potential to form liposome-like analogs (azotosomes) in the methane-rich seas on Saturn’s moon, Titan. Based on his talk, he was invited to participate in the plenary session the following day for the Jet Propulsion Laboratory audience. These interactive KISS workshops “develop revolutionary concepts and technology for future space missions… as a ‘think and do tank.’ “
Cornell graduate students, Nikita Sengar and Blaire Sorenson, members of the Clancy group in Chemical Engineering, have been selected to receive two of the twelve travel grants available to attend the Macromolecular Simulation Software workshop in Jülich, Germany in October. The workshop is funded by NSF’s Advanced Cyberinfrastructure and Chemistry division and will be led by Professors Cecilia Clementi (Rice) and Shantenu Jha (Rutgers). The goal of the workshop is to “promote interaction between end users and software developers” in the increasingly decentralized software environment needed to attack challenges in molecular simulation. Sengar is investigating how organic semiconductors might be used to select specific sizes of carbon nanotubes, a joint project with Princeton University (Loo group). Sorenson is focusing on nucleation processes in perovskite materials for photovoltaics.
Clancy group member, Victoria Sorg, passed her examination for Admission to Candidacy to the PhD (8/11/15) with flying colors. Tori gave a masterful introduction of the use and advantages of laser spike annealing InGaAs samples. The highlight of her talk was a dramatic (20%) improvement in carrier concentration as a result of their LSA treatment. This work has been presented to SRC member companies via an “e-Workshop” and in our annual SRC review. Tori is the first author on a recently accepted invited ECS paper describing this work. She is expected to graduate in 2017.
Ms. Jovana Andrejevic, AEP ’16 at Cornell has been awarded a GlobalFoundries/SRCEA (Semiconductor Research Corporation Education Alliance) student scholarship that “recognizes and rewards aspiring and leadership-oriented engineers interested in the semiconductor industry. This exciting scholarship is for students who demonstrate solid ambition and promise in their academic and professional efforts.” In addition to a financial scholarship prize, Jovana will receive an all-expenses paid trip to TECHCON in Fall 2015. Jovana was rewarded for her academic performance and her innovative research in computational method development. She has developed models that capture the nucleation and growth of non-traditional materials of interest to the semiconductor field, including colloidal lead chalcogenides and perovskites. Her work, mentored by senior PhD candidate James Stevenson, is being prepared for publication this summer.
Mardochee Reveil was presented with the “First Year Graduate Student of the Year” award by the Cornell office of Diversity Programs in Engineering on Friday May 8th. for his outstanding progress in research. Mardochee joined the Clancy group in November 2014 following his MS degree from Syracuse University. In just his first six months as a PhD student, he successfully extended a software suite called CLASP (Cornell Laser Annealing Simulation Package) to include non-traditional materials like InGaAs, which is a candidate to replace silicon in future semiconductor devices. CLASP is used by a number of semiconductor industries such as GlobalFoundries and Novellus. Mardochee was also selected from a very competitive pool to be a participant in a CECAM workshop on multiscale modeling at the Les Houches School of Computational Physics taking place fromMay 11-22 2015 in France.
Suki Zhang successfully defended her MS thesis on May 5th 2015. Her thesis describes the ability of Laser Spike Annealing to improve dopant activation in InGaAs over traditional, slower, heating processes like furnace annealing or RTA. Suki will join the PhD program at Purdue University in ECE this summer. Congratulations, Suki; we will miss your enthusiasm and smiling face in the lab.
