Carlo Pignedoli received his PhD in Physics in 2001 from the University of Modena (Italy) and joined Empa, the Swiss Federal Laboratories for Materials Science and Technology after post-doctoral research fellowships at the University of Modena (Italy) and at the IBM Zurich Research Laboratory (Switzerland).
He is an expert in the simulation of the electronic and geometry properties of bulk semiconductors and interfaces,in the characterization of the atomistic mechanisms for chemical reactions at surfaces by means of abinitio methods, force fields and Monte Carlo methods. His atomistic simulations have been always focused on collaborations with experimentalists. This synergy allowed two major breakthroughs in his research:
During his work at IBM, in the team lead by Prof. Andreoni, research in the field of high-k materials contributed to the “establishment” of hafnium silicates as material to replace silicon oxide in the CMOS produced since second half of the ’00s. The research effort was acknowledged by a joint IBM Intel press release (March 2007).
In the field of surface supported chemistry, related to carbon nanostructures, a major achievement was the understanding of the atomistic details that characterize the metal supported cyclodehydrogenation reaction that is at the basis of the synthesis procedure introduced by the team lead by Prof. Fasel, to fabricate nanometer wide graphene nanoribbons with atomic precision.
Carlo Pignedoli is currently Senior Scientist and Deputy Group Leader of the Atomistic Simulations Group of the nanotech@surfaces Laboratory of Empa.
