Shaowei Li is a Heising-Simons Postdoctoral Fellow in the Physics Department, appointed from Fall 2018 to Fall 2020. His research focuses on developing a novel imaging technique combing laser and a scanninbg tunneling microscope (STM) to shatter the diffraction limit and probe the inhomogeneous properties in low dimensional materials. The desire for observing finer details using optical microscopy particularly in bio-science and material-science is pushing technology developments beyond the diffraction limit. The coupling of photon excitation with electron tunneling at the junction of a scanning tunneling microscope combines the femtosecond sensitivity of a laser and the Angstrom resolution of tunneling electrons. The joint fs-A resolution will provide a new window for viewing the unique ultafast dynamics of individual nano-scale objects.
Shaowei received his Ph.D. in physics from UC Irvine in 2017. Prior to that, he received his bachelor degree in physics from Nankai University in 2010. He spent a year as a postdoctoral fellow at Northwestern University before joining ENSI. His past work involves probing the physcial and chemical properties of single molecules and low-dimensional materials with optical techniques and STM.
