Brief CV:

Luca Morassi was born in Mirandola (Mo), Italy, on September 15th, 1982.

From July 2008 to February 2009 he was in IMEC (Interuniversity MicroElectronics Centre, Leuven, Belgium) for an internship; during this period he worked on the characterization of High-k-based composed stack for MOSFETs (Metal Oxide Semiconductor Field Effect Transistor) gate oxide. In 2009 he received his academic master degree in Electronic Engineering from University of Modena e Reggio Emilia, Italy - Topic: "Characterization and Simulation of High-k Dielectrics for Innovative Non-Volatile Memories". During 2009 he collaborated with University of Modena and Reggio Emilia with a research activity focused on the electrical characterization of high-k material for Non-Volatile Memory (NVM) devices. Since 2010 he is a PhD student at ICT Electronics & Telecommunications Doctorate School, Modena, Italy with a research activity based on III-V compound semiconductor. His main research field is the characterization of InGaAs-channel MOSFETs and MOSHEMTs (Metal Oxide Semiconductor High Electron Mobilty Transistors) for high power and logic applications.
