Colloidal semiconductor nanocrystals exhibit unique and highly tunable physical and chemical properties that make them very promising for application in opto-electronic devices and biological platforms. In these nanocrystals a large fraction of all atoms are located at surface or interface sites. These surface and interface atoms critically determine the outcome of nanocrystal synthesis, physical and chemical characteristics as well as the performance of quantum-dot based devices.
Understanding, controlling and adjusting the termination of nanocrystal surfaces has thus become a most exciting part of semiconductor nanocrystal research. Over the last 10 years, the joined pull-and-push by application development, where device performance invariably proves to be linked to surface termination, and new surface characterization methodologies has turned surface chemistry into an enabling science for colloidal quantum dot research. The NanoGe FQDots17 meeting will bring together scientists to discuss surface chemistry of colloidal semiconductor nanocrystals in all its aspects, address challenges and identify future research directions.
- Experimental and theoretical studies on surface termination in semiconductor nanocrystals
- The effect of surface chemistry on nanocrystal synthesis and the formation of nanocrystal assemblies
- The impact of surface chemistry on the physical properties of nanocrystals and nanocrystal assemblies and the performance of nanocrystal based devices
- Advanced applications of colloidal nanocrystals made possible through surface chemistry such as (photo)catalysis and sensing

Patanjali Kambhampati. BA Carleton College USA (1992), PHD University of Texas (USA) 1998, PDF University of Texas (USA) 1999 - 2001. Professor of Chemistry McGill University (2003 - present). Research focus of semiconductor nanostructures and femtosecond laser spectroscopy.
Maksym Kovalenko has been a tenure-track Assistant Professor of Inorganic Chemistry at ETH Zurich since July 2011 and Associate professor from January 2017. His group is also partially hosted by EMPA (Swiss Federal Laboratories for Materials Science and Technology) to support his highly interdisciplinary research program. He completed graduate studies at Johannes Kepler University Linz (Austria, 2004-2007, with Prof. Wolfgang Heiss), followed by postdoctoral training at the University of Chicago (USA, 2008-2011, with Prof. Dmitri Talapin). His present scientific focus is on the development of new synthesis methods for inorganic nanomaterials, their surface chemistry engineering, and assembly into macroscopically large solids. His ultimate, practical goal is to provide novel inorganic materials for optoelectronics, rechargeable Li-ion batteries, post-Li-battery materials, and catalysis. He is the recipient of an ERC Consolidator Grant 2018, ERC Starting Grant 2012, Ruzicka Preis 2013 and Werner Prize 2016. He is also a Highly Cited Researcher 2018 (by Clarivate Analytics).
Joseph M. Luther obtained B.S. degrees in Electrical and Computer Engineering from North Carolina State University in 2001. At NCSU he began his research career under the direction of Salah Bedair, who was the first to fabricate a tandem junction solar cell. Luther worked on growth and characterization high-efficiency III-V materials including GaN and GaAsN. His interest in photovoltaics sent him to the National Renewable Energy Laboratory (NREL) to pursue graduate work. He obtained a Masters of Science in Electrical Engineering from the University of Colorado while researching effects of defects in bulk semiconductors in NREL�s Measurements and Characterization Division. In 2005, He joined Art Nozik�s group at NREL and studied semiconductor nanocrystals for multiple exciton generation for which he was awarded a Ph.D. in Physics from Colorado School of Mines. As a postdoctoral fellow, he studied fundamental synthesis and novel properties of nanomaterials under the direction Paul Alivisatos at the University of California and Lawrence Berkeley National Laboratory. In 2009, he rejoined NREL as a senior research scientist. His research interests lie in the growth, electronic coupling and optical properties of colloidal nanocrystals and quantum dots.
Jonathan Owen received a B.S. in Chemistry from the University of Wisconsin-Madison, and a Ph.D. in Chemistry from CalTech. As a graduate student in the lab of Professor John Bercaw he studied the kinetics and mechanism of methane C-H activation. In 2005 he joined the lab of Professor Paul Alivisatos as a Petroleum Research Fund Alternative Energy Fellow to study the crystallization and derivatization of colloidal semiconductor nanocrystals. In 2009 he joined the faculty at Columbia University as an Assistant Professor of Chemistry where his group continues to study the synthesis and surface chemistry of colloidal semiconductor nanocrystals. For this work, he has received early career awards from the Department of Energy, the National Science Foundation, 3M, and DuPont.
