| Biography |
| Dr Quek Su Ying is currently an Independent Investigator in the Institute of High Performance Computing (IHPC), and adjunct Assistant Professor in the Division of Physics and Applied Physics at NTU. Prior to joining IHPC in 2011, she spent four years at Lawrence Berkeley National Laboratory where she did post-doctoral studies with Dr Jeffrey B. Neaton in the Molecular Foundry. She obtained her Ph.D. in Applied Physics with Professor Efthimios Kaxiras from Harvard University in 2006 and Bachelors degree in Mathematics from the University of Cambridge in 2000. Together with her collaborators, she developed a practical and predictive approach for describing electron transport in molecular electronics, and demonstrated the world’s first mechanically controllable single-molecule switch. She has published in internationally-refereed journals including Nature Nanotechnology, Physical Review Letters and Nano Letters, with more than 300 citations (excluding self-citations) as of March 2012. |
| Research Interests |
The focus of my research group is ‘Materials Design for Next Generation Electronics, Spintronics and Thermoelectrics’. With Moore’s law and advances in nanoscale materials synthesis, next generation devices will be one million times smaller than a mosquito. Charge transport at such length scales is fundamentally different from that in present-day macroscopic devices.
We use first principles approaches (i.e. approaches with well-defined approximations but no adjustable parameters) to make predictions on the electronic structure and transport properties of different material systems, such as graphene, topological insulators and single-molecule junctions. The uniqueness of our approach is that we can combine many-electron theories with mean-field theories into a practical and predictive tool to predict transport properties in nanoscale systems. We also work closely with experimentalists to understand experimental observations and guide experiments. |
