报告摘要:
Colloidal nanoplatelets are atomically flat, quasi-two-dimensional sheets of semiconductor that can exhibit efficient, spectrally pure fluorescence. Despite intense interest in their properties, the growth mechanism behind their highly anisotropic shape and precise atomic-scale thickness remains unclear, and even counter-intuitive for commonly studied nanoplatelets. Here we will explain how simple growth kinetics can lead to such materials. Knowledge of this previously unknown mechanism for controlling shape at the nanoscale can then lead to broader libraries of quasi-two-dimensional solids.
报告人简介:
David J. Norris (B.S. Chemistry, University of Chicago, 1990; Ph.D. Chemistry, MIT, 1995) started his independent research career at the NEC Research Institute in Princeton in 1997. He then became an Associate Professor (2001-2006) and Professor (2006-2010) of Chemical Engineering and Materials Science at the University of Minnesota. In 2010, he moved to ETH Zurich where he is currently Professor of Materials Engineering and Head of the Department of Mechanical and Process Engineering. Professor Norris has received the Credit Suisse Award for Best Teaching, the Max Rössler Prize, an ERC Advanced Grant, and the ACS Nano Lectureship Award. He is a Fellow of the American Physical Society and the American Association for the Advancement of Science, and an editorial board member for ACS Photonics and Nano Letters. His research focuses on how materials can be engineered to create new and useful optical properties.
