On March 4th, Judy Cha presented “Watching Atoms Move.” If Elvis had been a scientist, he would have become a materials physicist just to watch atoms shake, rattle and roll. Students listened to Prof. Judy Cha tell them about the tools she uses to not only watch atoms move, but also to manipulate them into structures one atom at a time.
Time: Demonstrations by Synapse of Yale Scientific Magazine from 10am - 11am; Talk from 11am - noon.
About Judy Cha: Cha is the Carol and Douglas Melamed Assistant Professor of Mechanical Engineering & Materials Science at the Yale School of Engineering & Applies Science, with an affiliation at the Energy Sciences Institute on West Campus. Professor Cha has made important contributions to materials physics, both in the field of electronic materials and glass physics. The selection committee noted her frequent and consistent presence in top journals in her field, as well as her interdisciplinary contributions, which are supported by both the National Science Foundation and the U.S. Department of Energy. Professor Cha is in the vanguard connecting rational design principles to synthesis and function of tomorrow’s essential electronic materials.
The Cha research group focuses on synthesis and transport measurements of two-dimensional layered nanochalcogenides, in particular topological insulator nanoribbons and nanoplates. The group uses analytical scanning transmission electron microscopy and electron energy-loss spectroscopy to investigate the fundamental structure-property relationships of the synthesized nanomaterials for novel electronic, photonic, and plasmonic properties. Other chalcogenide systems are also investigated for energy applications.
