Harvard University: SiOnyx Founder Eric Mazur with four his students won SPIE Green Photonics Award for Laser-assisted Manufacturing and Micro/Nano Fabrication. The winning paper was written by Eric Mazur, the Balanski Professor of Physics and Applied Physics, with graduate students Benjamin Franta (lead author), Meng-Ju Sher, and Katherine C. Phillips in the Harvard Department of Physics, and Yu-Ting Lin at Harvard School of Engineering and Applied Sciences.
The group used femtosecond laser pulses to modify and control both the chemical composition and the surface structure of silicon. These modifications affect the optical and electronic properties of the material that they called "black silicon" with a potential for use in novel photosensitive devices.
The award will be presented on January 25, 2012 at SPIE Photonics West in San Francisco.
