• Sommario/riassunto: Frank Ortmann is Head of the Computational Nanoelectronics group at the Institute for Materials Science at the Technische Universität Dresden, Germany. He is specialized on large-scale electronic transport simulations linked with ab initio electronic structure methods and on nanoelectronics of materials. Frank Ortmann studied physics at the University of Jena, Germany, where he received his PhD for a work on the topic of charge transport in organic crystals in 2009. He moved to the French Commissariat a l'Energie Atomique et aux Energies Alternatives Grenoble, France, for a postdoctoral stay f
