Résumé:
In this seminar, I will present recent results connected to two-dimensional materials with a special emphasis on the effect of their defects. Most of this work [1-3] is done using the BigDFT package that allows to properly describe surfaces at the DFT level (http://bigdft.org). Next, I will describe how one can rationalize interface misfit dislocations in two dimensions [4]. Finally, I will discuss how atomic scale description allows understanding the tailoring of graphene properties [5-6].
