SUMMARY:Quantum Dot-based Opto and Nano Electronic Devices
DESCRIPTION:Abstract\nColloidal quantum dots (QDs) have been of great interest owing to the unique optical and electrical properties\, such as size-dependent band gap tunability\, wide absorption and narrow emission spectra\, and controllable surface properties. Recently\, several types of opto- and nano-electronic devices utilizing QDs have been reported for future optoelectronics. The QD-based light-emitting diodes\, QLEDs\, are one of the most promising devices for future full-color displays and new types of light sources. However\, fundamental mechanisms\, such as charge injection into QDs\, exciton recombination\, and operational stability\, should be understood and improved more to commercialize the QLED displays. In this talk\, I will mainly present our recent research progress on QLEDs\, including device design to improve device performance and to understand operational mechanisms. Also\, I will briefly introduce the QD-based memristors for neuromorphic computing. \nSpeaker\nProf. Jeonghun KWAK\nAssociate Professor\,\nDepartment of Electrical and Computer Engineering\,\nSeoul National University \nBiography of the Speaker\nProf. Jeonghun KWAK received his B.S. (2005) and Ph.D. (2010) degrees in Electrical Engineering from Seoul National University (SNU)\, Korea. After working as a postdoctoral researcher at SNU for one year\, he worked as an assistant/associate professor at Dong-A University\, Korea (2011–2015) and at the University of Seoul\, Korea (2015–2019). Since March 2019\, he has been an associate professor at the Department of Electrical and Computer Engineering\, SNU. His current research interests focus on opto- and nano-electronic devices\, such as QLEDs\, organic thermoelectric devices\, and neuromorphic devices based on organic molecules and low-dimensional materials. \nOrganizer\nProf. Leo Tianshuo ZHAO \nAll are welcome! We look forward to seeing you!
