    Center for Functional Nanomaterials Seminar

    11 am, Bldg 735, Conference Room B, 1st Floor

    Monday, January 26, 2015, 11:00 am

    Hosted by: Chang-Yong Nam

    Nanocrystals measure around one billionth of an inch and they can be metals, semiconductors, or insulators. They are the smallest objects we can synthesize on the nanoscale and are used as enabling materials for diverse applications with unmatched tunability and versatility. My talk focuses on how we can utilize these nanomaterials for direct conversion into electricity of two of the most important ubiquitous sources of free energy: sunlight and waste heat. Unlike fossil fuel plants, direct energy conversion devices have no moving parts. They are silent, and require no maintenance, since "electrons and holes do all the work". This presentation details how in solar cells, we can "maximize the number of electrons and holes that do the work" and in thermoelectrics, engineer the material so that the "electrons or holes do the work better." Short biography of Dong-Kyun Ko: Dong-Kyun Ko is currently an Assistant Professor of Electrical and Computer Engineering at NJIT. He received his BS in Materials Science and Engineering from Yonsei University (Korea, 2005). He received his MS (2007) and PhD (2011) degrees in Materials Science and Engineering from the University of Pennsylvania, advised by Dr. Christopher Murray. After his PhD, he held a joint appointment with Dr. Vladimir Bulovic's and Dr. Moungi Bawendi's labs at MIT as a Postdoctoral Associate. Dong-Kyun's research focuses on energy materials and devices utilizing colloidal semiconductor nanocrystals (quantum dots). Specifically, he is interested in developing more efficient solar and thermal energy harvesting devices by manipulating matter at the nanoscale. His research involves multidisciplinary approaches that span from physics, chemistry, and materials science to electrical engineering.
