TITLE:  From chemical bonds to high mobility in layered materials


In the discipline of chemistry, it is common to have guidelines and heuristics that help to predict how chemical reactions will proceed. We are interested to expand these heuristics to understand electronic properties in inorganic solids. In this talk, I will show how delocalized chemical bonds in structural networks helped us to identify a layered van der Waals material with very high mobility, which also is antiferromagnetic. In addition, this material can be mechanically exfoliated.

The second part of my talk will focus on the concept of chemical exfoliation. With this method, we can exfoliate materials for which the scotch tape method fails. I will show how we were able to synthesize a new chromium chalcogenide this way, which might be a new 2D magnetic material.
