Yingying ZHANG, Associate Professor
Dr. Zhang received her Ph.D. degree in chemistry from Peking University in 2007. From Jun. 2008 to Jun. 2011, she worked in Los Alamos National Laboratory (USA) as a postdoctoral research associate. She joined the Center for Nano and Micro Mechanics (CNMM) in Tsinghua University as an associate professor in July of 2011.
She has been working on engineering of nanomaterials and nanostructures since she was a PhD student. Her research is mainly in the field of synthesis and applications of carbon nanomaterials. Her research results include: 1) Investigated the effect of catalysts pretreatment on the growth of vertical aligned CNT arrays and realized the controlled growth of spinnable CNT arrays (enabling the drawing of continuous CNT yarns and ribbons from the array); 2) Demonstrated the fabrication and unique properties of composites with aligned CNTs, including transparent stretchable conductor CNT/PDMS film and superconducting CNT/carbides; 3) Investigated Raman spectrum variation and electronic band-gap engineering along axial direction of individual SWNTs induced by substrate-nanotube interaction; 4)Demonstrated the remarkable laser heating effect on suspended SWNTs and the diameter/chirality-dependence of temperature effect on the Raman Radical Breathing Modes of individual SWNTs.
She has authored more than 20 peer-reviewed scientific journal papers (with more than 160 citations by June,2011), 10 presentations on international conferences and 3 patents. She also serves as a reviewer for more than 20 international journals, including Nature Nanotechnology, Advanced Materials, Advanced Energy Materials, Carbon et al.
1. Controlled synthesis, assembly, heterostructures and composites of 1D and 2D nanocarbon materials (including single/multi-walled carbon nanotubes and graphene);
2. Mechanical and electrical properties of nanocarbon materials for nanodevice applications.
