2 new publications

We have published two new publications to the topics "unusually small band gap" and "Topological Stone–Wales Defects Enhance Bonding"

First thesis defences in Leipzig

Jakob Schramm, Luisa Kärmer and Robert Jahn have successfully defense her Bachelor-Thesis and Hendrik Weise his Master-Thesis. It was the first theses of the group in Leipzig. Congratulations to Jakob, Luisa, Robert und Hendrik.
