Electronic Properties of 2D Transition Metal Carbides and Nitrides (MXenes)

29.08.2019 (Thursday) , 15:00 - 16:30
Walther-Hempel-Building, Room HEM 219 , Mommsenstr. 4 , 01069 Dresden

Everybody welcome!

2D transition metal carbides and nitrides (MXenes) are a large family of 2D materials with more than
30 compositions experimentally synthesized and a few dozens more predicted to be stable and
studied computationally. They benefit from their high electrical conductivity, wide range of optical
properties, hydrophilic surface, and high mechanical strength. Because of those properties, they
show promise in a wide a variety of applications from energy storage to photonics. In this talk, an
overview of fundamental electronic properties of MXenes are presented and discussed. Specifically,
the roles of intra- and inter-flake electronic conduction on the temperature-dependence of resistivity
of MXenes will be discussed in detail. Moreover, systematic investigation of the roles of MXene
composition, including the transition metals, the X elements (C and/or N), and surface terminations
on their electronic and transport properties will be presented.

Dr. Yury Gogotsi is Charles T. and Ruth M. Bach Chair Professor and Distinguished University
Professor of Materials Science and Engineering at Drexel University in Philadelphia, USA. He also
serves as Director of the A.J. Drexel Nanomaterials Institute. His research group works on 2D carbides
and nitrides (MXenes), nanostructured carbons, as well as other nanomaterials for energy, water and
biomedical applications. He has co-authored 2 books, 16 book chapters, about 700 journal papers,
edited 14 books, and obtained more than 50 patents. He was recognized as Highly Cited Researcher
in Materials Science and Chemistry (Web of Science) in 2014-2018. He has received numerous
national and international awards for his research. He also serves on the MRS Board of Directors and
acts as Associate Editor of ACS Nano.
