Shuchen Zhang of Purdue University will be presenting at the next Physics Colloquium. Please join the zoom-only presentation at 4:00 PM EST Thursday (October 6):
Templated-Synthesis of Low-Dimensional Materials and their Optoelectronic Properties
While many exciting properties are found in low-dimensional materials due to the quantum confinement effect, there remain difficulties in controlled synthesis, for example, in one-dimensional carbon nanotubes (1D CNTs) and two-dimensional (2D) perovskites. Therefore, we put forward the templated-synthesis methods to address this issue. For CNTs, we designed catalysts with high melting points as the nucleation template to epitaxial grow single-chirality CNTs (Nature 2017). More recently, we created 2D RP phase perovskites as the template to synthesize ultra-thin APbX3 (X=I, Br) perovskites. We further created perovskite moiré superlattices and experimentally explored their angle-dependent moiré potentials for the first time.
Dr. Shuchen Zhang received his Bachelor's degree (Chemistry) from Shandong University (China) in 2008 and his Ph.D. degree in Physical Chemistry from Peking University (China) in 2017. He was a postdoctoral researcher at Peking University as a “Boya” fellow. In 2019, he joined Lawrence Berkeley National Lab (LBNL) as a postdoctoral fellow with Prof. Gabor Somorjai. Since 2020, he has been a postdoctoral researcher at Purdue University. His primary research is realizing the structure-controlled synthesis of low-dimensional materials and exploring the exciting properties. Dr. Zhang will be an Assistant Professor at Peking University from Dec 2022.
