Interfacial Engineering in 2D Materials
Speaker Prof Kaihui Liu
Date 3 August 2017 (Thursday)
Time 15:00 – 16:00
Venue Room 4503 (Lifts 25-26), HKUST
In the point view of surface sciences, 2D materials are very nice systems in terms that their electronic/phonon states are mainly at the surface. Therefore interfacial interaction is a very powerful freedom to control the physical properties and growth dynamics of 2D materials. In this talk, we will first introduce the joint technique of in-situ TEM and ultrafast nano-optics and then give several examples on the studies of interfacial engineering in 2D materials, including interlayer coupling in MoS2 bilayers, ultrafast charge transfer in MoS2/WS2 bilayers, ultrafast graphene growth, and epitaxial graphene growth.
About the Speaker
Prof Liu got his bachelor degree from Beijing Normal University in 2004 and his ph.D degree from Institute of Physics, Chinese Academy of Sciences in 2009. After that he worked as a postdoctoral fellow at Department of Physics, UC Berkeley. In 2014, he joined Peking University as the National Thousand Youth Talents Plan Professor of China. He is currently the Editorial Board Member for IOP Nano Futures and Nanotechnology. He won First-Class Science & Technology award of Beijing (2009), CPC "National Thousand Talents Plan for Young Scholars" award (2014), NSFC Excellent Youth Scholar (2015), Sub-project leader of National Key R&D Plan (2016), Ten "Xin Rui" Scholar of China (2017).
Prof Kaihui Liu’s main research interests are the novel physical phenomena and controllable growth in low-dimensional structures, especially of 1D carbon nanotubes and 2D materials. He developed an advanced single nano-object level in-situ Nano-optics + TEM technique, and in-situ Nano-optics + CVD technique to study the structure-dependent physics and growth mechanism at nano scale. He has published more than 60 scientific journals, including first-authored or correspondence-authored Nature Nanotechnology (3), Nature Physics, Nature Communications (3), PNAS, JACS (2), Advanced Materials (4), NPG Light, Nano Letters, and ACS Nano.
