报告人简介:
Dr. Dong Ick Son received the Ph.D. degree in Department of InformationDisplay Engineering from Hanyang University Korea, in 2010. After that, hejoined Korea Institute of Science and Technology (KIST) as a star post-docduring 2010-2012. He worked as a visiting researcher in Department of Physics,KU Leuven, Belgium during post-doc period in 2011. Since 2012, he has worked asa senior research scientist in KIST and an Associate Professor at University ofScience & Technology (UST). His main research fields are study on opticaland electronic devices (nonvolatile organic bistable memory device,light-emitting device, photodetector, and photovoltaic cell) fabricatedutilizing hybrid organic/inorganic nanocomposites and study on applicationdevices utilizing hybrid van der Waals 2D materials (including carbonnanomaterials) and inorganic nanoparticles.
报告大纲:
Recently, the van der Waals 2D materials (including carbon nanomaterials)has attracted due to numerous investigations into its remarkable physical,chemical, and mechanical properties, opening up a new research area formaterials science, chemistry and physics, and including for a diverse rangingand exiting potential applications.To manipulate 0D+2D, 2D+0D+2D hybrid materials usingthe assembly of low-dimensional nanomaterials of different dimensionalities,such as dichalcogenides (TMDs), hBN and quantum dots (0D), to control thebandgap of the hybridized structures, and to investigate emergent properties ofvertically-layered different dimensional composite materials andphotoelectronic devices.Here we employ a simplesolution method to prepare emissive hybrid quantum dots consisting of metaloxide quantum dots (QDs) core wrapped in a shell of single-layer graphene, anduse these QDs to make a white light-emitting diode. The intermediateconsolidated quasi-metal oxide-graphene core-shell QD is a kind of newlydeveloped material which will be appropriate for a functional layer acting asan electron transport layer with high mobility in the field of such as DSSC,photovoltaic devices, sensor, lithium ion batteries (LIBs), photodetector, fuelcells, and light emitting diode etc.
