[세미나]Nanocrystal Quantum Dot Assemblies for Energy Applications
교육과학기술부 글로벌프론티어 (재)멀티스케일 에너지 시스템 연구단 (단장: 최만수 교수) 은 나노기술과 에너지 기술의 융합을 통하여 혁신적 미래 광에너지와 분자에너지 원천기술 개발을 목표로 하는 멀티스케일 에너지 시스템 연구사업을 추진하고 있습니다. 연구단에서는 격주로 멀티스케일 에너지 강좌를 개최하고자 합니다. 관심 있는 분들의 많은 참석 바랍니다.
1. 제 목 : Nanocrystal Quantum Dot Assemblies for Energy Applications
2. 연 사 : 정소희 박사 (한국기계연구원 나노역학연구실)
3. 일 시 : 2012년 4월 23일 (월) 16:00 ~ 17:00
4. 장 소 : 서울대학교 신공학관(301동) 117호 세미나실
5. Abstract : Colloidal Nanocrystal Quantum Dots (NQDs) have been considered ideal building blocks for functional materials because of their physical properties tunability based on quantum confinement effect. Recent advances in the use of hot carriers and multiple-excition from the high energy photon in NQDs have demonstrated potential efficiency improvements when used in photovoltaics. Here, strategies to facilitate carrier transfer/transport while preserving optical characteristics of isolated NQDs will be discussed. Specifically, synthesis and characterizations of 1) the fabrication of neat NQD solids (assembled NQD films) with modified surfaces by attaching ligands or by applying physical processes such as heat annealing [J. Phys. Chem. C (2011), 115(3), 607] and 2) coupling NQDs to one-dimensional nanostructures such as single-walled carbon nanotubes (SWNTs) [ACS Nano, (2010) 4(1), 324] will be presented. 6. 약 력 : 1. Senior Researcher (2006 present), KIMM. 2. Visiting Scholar (2010-2011), National Renewable Energy Lab. (Nozik Group) 3. Post Doc. (2005-2006), Los Alamos National Lab. (Klimov Group) 4. Ph. D. (2005), Chemistry, University of Michigan (LANL since 2003) 5. M. S. (1997), Chemistry, KAIST, Korea 6. B. S. (1995), Chemistry, KAIST, Korea 7. Research interests: Large-scale Synthesis of Nanocrystal Quantum dots (NQDs), Charge/energy transfer in NQD/NQD-hybrids arrays, NQD based applications including photovoltaics and light emitting diode
