How graphene sheets respond to force

11. November 2014

Bogdan and Frauke have published two back-to-back articles (one together with the former member of the MBM group Dr. Ilona Baldus) studying the force and stress distribution in a sheet of graphene indented by an Atomic Force Microscopy tip until rupture. They developed a new potential to model the carbon-carbon bond breaking in a simple and efficient, yet realistic way. Using it in simulations of up to several million atoms, they closely reproduce experimental result of graphene rupture and find a highly focused mechanical stress to be the cause of material failure.

In a number of projects, FDA also helped to reveal the mechanism of allostery in proteins. More details are given here.

About HITS

The Heidelberg Institute for Theoretical Studies (HITS) was established in 2010 by the physicist and SAP co-founder Klaus Tschira (1940-2015) and the Klaus Tschira Foundation as a private, non-profit research institute. HITS conducts basic research in the natural sciences, mathematics and computer science, with a focus on the processing, structuring, and analyzing of large amounts of complex data and the development of computational methods and software. The research fields range from molecular biology to astrophysics. The shareholders of HITS are the HITS-Stiftung, which is a subsidiary of the Klaus Tschira Foundation, Heidelberg University and the Karlsruhe Institute of Technology (KIT). HITS also cooperates with other universities and research institutes and with industrial partners. The base funding of HITS is provided by the HITS Stiftung with funds received from the Klaus Tschira Foundation. The primary external funding agencies are the Federal Ministry of Education and Research (BMBF), the German Research Foundation (DFG), and the European Union.
