Research

Carbon nanotubes: Recently we developed a technique whereby large quantities of nanotubes can be grown at high temperatures. These very high-quality nanotubes have been used to fabricate flat panel displays.

Photonic crystals: An exciting development has been the fabrication of a ZnO-based photonic crystal that can also lase. This work will lead to the integration of nanophotonic devices in the UV optical regime.

Random lasing phenomenon: In collaboration with colleagues in physics, we have succeeded in making the first observation of the random lasing effect in a ZnO powder layer. We have also made the world's smallest laser, a 1.5- micron ZnO particle cluster.

Quantum dots and wires: Work is in progress to synthesize and study quantum phenomena in quantum dots and nanowires of oxide-based materials.

Biography

R.P.H. Chang received his B.S. degree in Physics from the Massachusetts Institute of Technology and his Ph.D in Astrophysics from Princeton University. He worked at Bell Laboratories before joining Northwestern University in 1986 as Professor of Materials Science and Engineering and Professor of Electrical and Computer Engineering.
Prof. Chang served fourteen years as director of Northwestern’s Materials Research Center, where he established several large research programs in carbon science and technology and complex oxide films and devices. In 1993, he founded the Materials Research Institute as a platform for expanding his diverse activities in materials research, education, and network building. An enthusiastic proponent of interdisciplinary science education, Prof. Chang has created several groundbreaking programs that bring cutting-edge science concepts into pre-college level classrooms. He established and currently directs the Materials World Modules (MWM) program for middle school science classrooms and also directs the National Center for Learning and Teaching in Nanoscale Science and Engineering (NCLT), recently established by the NSF to help meet the research and workforce development goals of the U.S. National Nanotechnology Initiative. In 2005, he was honored by the National Science Foundation as a Director's Distinguished Teaching Scholar (DTS) for his groundbreaking results in research, strong teaching and mentoring skills and major educational contributions.
A member of numerous international advisory boards, Prof. Chang is also a former Present of the Materials Research Society and the founding president of the International Union of Materials Research Societies (IUMRS). His current research interests include nanostructured solar cells, carbon nanotubes, photonic crystals, random lasing phenomenon, and quantum dots and wires.
Prof. Chang works actively to serve the global community. Since 1995, he has organized workshops in Africa, Asia, Europe, the Americas, and the Middle East to promote international collaborations and create a Materials World Network. Since 2001, he has been leading the establishment of the Global Nanotechnology Network (GNN).
