报告题目：Nanogap-Enhanced Raman Scattering (NERS)
报告人：Yung Doug Suh教授
Raman scattering can provide a wealth of molecular chemical information, but it is basically a highly inefficient inelastic light scattering process between photon and molecule with a very small cross-section, meaning that very strong and controllable amplification mechanism, such as SERS, TERS, or NERS, is needed to obtain measurable and reliable signals.
In this talk, I will overview recent breakthroughs, advances, application, and prospects of plasmonic nanogap-enhanced Raman scattering with metal nanogap particles revealed by single-molecule/single-particle-level Nano Raman spectroscopy showing that these plasmonic nanogap particles can generate ultra-strong, quantifiable Raman signals in a highly reproducible manner.
Prof. Dr.Yung Doug Suh studied at Seoul National University for his BS(1991), MS(1993), and PhD(1999) under the guidance of Prof. Seong Keun Kim in Chemistry Department, Prof. Young Kuk in Physics Department, and Dr. Dongho Kim in Korea Research Inst. of Standards and Science (KRISS)researching gas phasemolecular reaction dynamics, surface physics with UHV-STM, and laser spectroscopies, respectively. After finishing his Postdoctoral research in ETH Zurich working with Prof. Renato Zenobi in 1999-2000,where he co-invented TERS(Tip-enhanced Raman Scattering), he worked at the Pacific Northwest Nat’l Laboratory (PNNL), USA, in 2001-2002 doing single molecule spectroscopy. He accepted a recruited principal research scientist position in 2003, to form his own research group: Laboratory for Advanced Molecular Probing (LAMP) at the Korea Research Institute of Chemical Technology (KRICT) in DaeJeon, South Korea. He is currently a group leader of Laboratory for Advanced Molecular Probing (LAMP), KRICT, and also serves as a full professor of Chemical Engineering Department, SungKyunKwan Univerisity (SKKU), Korea.
