CEE Students Selected for Best Oral Presentation

Two CEE students selected for Best Oral Presentation at the 2009 Engineering Graduate Symposium.| Short Read

The 2009 Engineering Graduate Symposium was held on north campus on November 13. The day-long symposium was a college-wide event focused on doctoral and master’s programs and graduate student research. The event was open to all College of Engineering current undergraduate and graduate students as well as prospective graduate engineering students from other institutions. Current graduate students had an opportunity to give a technical presentation. From the Civil, Environmental and Atmospheric Sciences category, Best Oral Presentation was given to Remy Lequesne and Mustafa Saadi, first and second place respectively.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
