Templated-Synthesis of Low-Dimensional Materials and their Optoelectronic Properties

Abstract: 

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.

Biography: 

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.
