Single Crystalline Semiconductor Nanomembrane-Based Fast Flexible Electronics & Optoelectronics

Research in electronic nanomaterials, previously dominated by studies of nanowires and nanotubes, now incorporates a growing focus on sheets with nanoscale thicknesses, referred to as single crystalline nanomembranes. Such materials have practical appeal because their two-dimensional geometries facilitate integration into devices, with realistic pathways to manufacturing. Recent advances in synthesis provide access to nanomembranes with extraordinary properties in a variety of configurations.
In this talk, an introduction tothe synthesis of various types of single crystalline nanomembranesbased on Si, Ge, and III-V will be given. After a general overview, the recent progressinsemiconductor nanomembrane based electronic/optoelectronic applications such as transistors and photosensorsand theirunique physical and mechanical properties will be covered.Finally, emerging methods for deterministic assembly of nanomembrane toward advanced heterostructures, which are impossible to demonstrate with conventional fabrication process, will be presentedin order to address compelling opportunities for research on the development of novel heterostructures and their applications of future functional electronics.


Jung-Hun Seo received a B.S. and M.S. degrees in electronics and electrical engineering from Korea University, Seoul, Republic of Korea, in 2006, 2008, respectively. He received an M.S. and a Ph.D. degree in electrical and computer engineering at the University of Wisconsin-Madison, USA. in 2011 and 2014, respectively. Since 2016, he has been with the Department of Materials Design and Innovation, University at Buffalo, as an Assistant Professor. He is the author or coauthor of more than 80 peer review papers and book chapters. His current research interests include semiconductor materials, processing and heterogeneous integration, semiconductor device physics and technologies, high-speed electronic and optoelectronic devices based on transferable semiconductor nanomembranes.

Colloidal Semiconductor Nanocrystal Photocatalysts: Teaching an Old Dot New Tricks

For example, in light-driven proton reduction to molecular hydrogen, a light-absorbing molecule (the photosensitizer) rapidly transfers a photoexcited electron to a catalyst for reducing protons. We recently found that CdSe quantum dots (QDs) and simple aqueous Ni2+ salts in the presence of a sacrificial electron donor form a highly efficient, active, and robust system for photochemical reduction of protons to molecular hydrogen. Ultrafast transient absorption spectroscopy studies of electron transfer (ET) processes from the QDs to the Ni catalysts reveal extremely fast ET, and provide a fundamental explanation for the exceptional photocatalytic H2 activity, as well as a guide to new directions for further improvements in efficiency.


Todd D. Krauss is currently the Chair of the Department of Chemistry and a Professor of Optics at the University of Rochester. He received his B.S., M.S., and Ph.D. in Applied and Engineering Physics all from Cornell University, the latter under the advisement of Professor Frank Wise. In 1998 he moved to Columbia University, serving as a postdoctoral research fellow under Professor Louis Brus, until 2000, when he joined the Chemistry faculty at the University of Rochester as an Assistant Professor of Chemistry. In 2006 he was promoted to Associate Professor and in 2008 he received a joint appointment in the Institute of Optics.  In 2010 Krauss was promoted to the rank of Professor of Chemistry and Optics, and assumed directorship of the Rochester Advanced Materials Program (formerly the Materials Science graduate program), which he held for three years. Krauss became Chair of the Department of Chemistry in July of 2013. Krauss's research interests involve fundamental physical and chemical studies of materials at the nanometer scale, down to the single molecule level, with a specific emphasis on colloidal semiconductor nanoparticles. Additionally, he is pursuing applications for these nanometer scale materials in the general areas of novel biological imaging agents, organic catalysis, and renewable energy. Krauss is a recipient of several honors and awards including a Camille Dreyfus Teacher-Scholar Award (2005), and an Alfred P. Sloan Research Fellowship (2004). He is a Fellow of the American Physical Society (2012) and the Optical Society of America (2014).
