Title: Engineering interfacial process for optoelectronic applications
Abstract:
Electron dynamics at semiconductor interface is a key issue for the performance of optoelectronic devices. In this talk, I'll show that some optoelectronic applications of semiconductor nanostructures may be substantially improved by engineering the interfacial electron dynamics in an ultrafast temporal scale. I'll start with two examples on designing biosensors and miniature lasers for neural sensing and photodynamic therapy applications by employing energy-transfer-coupled materials. After that, I'll talk about our recent study on the process of exciton fission in organic semiconductors with the aim of breaking the Shockley-Queisser limit in single-junction solar converters.

Short Bio:
Dr Zhang is serving as an associate professor of physics in National Laboratory of Solid State Microstructures and Department of Physics at Nanjing University. He obtained his B.S. degree in physics (2002) and Ph.D. degree in optics (2007) from Fudan University. In 2006, he was a visiting student at Christian Doppler Lab for Surface Optics, Linz University, Austria. He worked as a postdoctoral scholar at the Pennsylvania State University (2007-2010) before joining in Nanjing University in 2010. He has co-authored over 40 papers in peer-reviewed journals. His current research interests focus on understanding the physics of electron correlation, quantum coherence and interfacial interaction in multiple material systems for optoelectronic applications.
