Abstract

In this talk, I will give the perspectives of two-dimensional materials technology, when exploited in realistic applications, ranging from electronic (both digital and Radio Frequency), optoelectronic, and energy applications. This will be done from an engineering point of view. To achieve this goal, I will extensively take advantage of multi-scale simulations, based on ab-initio calculations to extract the main physical parameter at the atomic level (bands, effective masses, Hamiltonians etc.), to be included at a higher level of abstraction to device simulators, and up to circuit level.

Such an approach allows to i) provide design guidelines to the fabrication process, suggesting the most promising technological solutions, while discarding those, which clearly show poor performance even in the best case scenario; ii) understand physical effects observed in experiments.

About the speaker

Gianluca Fiori is with the University of Pisa. His main field of research includes the development of models and codes for the simulation of CMOS transistors with ultra-short channel and innovative devices based on new architectures and new materials. To this purpose, he has developed numerical codes, also through repeated research visits (in 2004, 2005 and 2008) at the Network for Computational Nanotechnology, at Purdue University, (IN-USA). Part of these models have been included into the commercial device simulator ATLAS, within a collaboration, in Autumn 2002, with Silvaco International, one of the worldwide leading developers and vendors of Technology Computer Aided Design (TCAD) software dedicated to Process and Device Simulation. Dr. Fiori has released, under the BSD open-source license, the in-house developed code NanoTCAD ViDES (http://vides.nanotcad.com), which includes most of the physical models implemented during his research activity.
