Light Interaction with Nanostructured Materials: Photovoltaics and Self-Assembly

Burns Lecture Hall, Keck Science Center
Understanding the physics of light interaction with nanostructures is useful for a variety of photonics applications. My research group uses electromagnetic simulations and microfabrication techniques to study how light travels through materials patterned on the scale of the wavelength of light. In the first part of the talk, I will discuss how nanostructure can be used to improve solar cell design. Our results have shown that patterning a material in the form of nanowires increases its optical absorption. These results will benefit the development of semiconductor solar cells. In the second part of the talk, I describe how the force of light on objects can be used to assemble nanomaterials. Our approach, which we call light assisted templated self-assembly (LATS), can arrange nanoparticles in specific 2D patterns, forming novel synthetic materials. Dr. Michelle Lynn Povinelli is the WiSE Gabilan Assistant Professor in the Ming Hsieh Department of Electrical Engineering at the University of Southern California. She is the recipient of an NSF CAREER Award, Army Research Office Young Investigator Award, Presidential Early Career Award for Scientists and Engineers (PECASE), and a TR35 Award for innovators under age 35 from MIT's Technology Review magazine. She received a BA from the University of Chicago, an MPhil from the University of Cambridge, and a PhD from MIT, all in Physics. She was a postdoctoral researcher in Electrical Engineering at Stanford University, where she won a L'Oréal For Women in Science Postdoctoral Fellowship. She has co-authored more than fifty journal articles, three book chapters, and three US Patents.
