Honda recently announced the winners of the first iDream Student Challenge at the 2010 Honda Initiation Grant Technical Horizon Symposium in Columbus, Ohio. With a focus on technologies that advance the quality of human life, the iDream Student Challenge is a scholarship program designed to inspire new thinking to everyday challenges and foster a spirit of innovation among the leaders of tomorrow.
This year’s competition included 19 teams of Ohio State science and engineering students whose projects offered creative engineering solutions and innovative technologies in one of three categories: electronics, mobility and materials. A total of $60,000 was awarded to the top three teams in each category as well as to the viewer’s choice winner, a team chosen via online voting. Five MSE students won a total of $14,000 prizes for their projects submitted to the iDream Student Challenge in Material Category.
Under the mentoring of Nitin Padture, one of the CEM supported REU students, Kelvin Hux and his teammate’s participanting project won the 1st place with $8,000 prize. Continue reading
Prof. Len Brillson, CEM Faculty member and IRG-2 co-Leader, has been chosen as a American Competitiveness and Innovation (ACI) Fellow for 2010 by the NSF Division of Materials Research. As part of the ACI Fellowship, Prof. Brillson will receive up to $360,000 in research funding from NSF. The ACI Fellowship citation states: “For establishing the optical signature of a leading defect in ZnO, opening the way to monitor and study processes that promote p-type conductivity, a major current objective in semiconductor optoelectronics. He is also recognized for his outstanding efforts in student mentoring and broadening participation of underrepresented groups in science.”
Please join us for a CEM Special Seminar

Dilute Nitrides and Flexible Electronics Research at NCA&TSU

Dilute nitrides are an exciting new class of semiconductors based on combining group III-N with III-V materials. The large differences in the electro-negativities between N and the cations in these alloys cause a vast band gap bowing as a function of composition. Thus, these alloys with a small amount of N permit rear possibility of simultaneous reduction in the band gap and the lattice parameter, with potential long wavelength emission in otherwise wide band gap III-V materials. A brief review of our work on different mixed As-Sb-dilute N alloys, namely GaAsSbN QWs, GaSbN QWs, InGaAsSbN QWs, and thick GaAsSbN/GaAs lattice matched epilayers, grown by molecular beam epitaxy (MBE) for various optoelectronic applications will be presented.
Flexible electronics is another area of ongoing research in our group. Results on the transparent low work function inorganic material, namely GaAlAsN grown by MBE, F-doped ZnO TCO films on PEN substrates by RF sputtering, and ZnO based alloy thin film transistors will be presented.

The Center for Emergent Materials and the Institute for Materials Research are proudly co-sponsoring the IMR Colloquium featuring Dr. Subra Suresh. Subra Suresh is the Dean of Engineering and Vannevar Bush Professor of Engineering at the Massachusetts Institute of Technology, where he has held joint faculty appointments in Materials Science and Engineering, Mechanical Engineering, Biological Engineering, and Health Sciences and Technology. Dr. Suresh will be giving a talk entitled, “Engineering the Future of Human Health” on Wednesday, May 5, 2010 at the Ohio Union U.S. Bank Conference Theatre located on 1739 North High Street. The talk will begin at 2:30-3:30 p.m. and a light reception will follow. For more information: http://imr.osu.edu/.
