The UCL/ICTEAM IEEE Student Branch is glad to invite you to the following seminar :
“Compact modeling and parameter extraction techniques of Organic Thin Film Transistors”
given by Benjamin Iñiguez, Pr., IEEE EDS Distinguished Lecturer, Full Professor at the Departament d’Enginyeria Electrònica, Elèctrica, i Automàtica, Universitat Rovira i Virgili, Tarragona, Spain.
The event will be held on Monday 27th of April 2015 at 2:30 pm in the Shannon meeting room (Maxwell A.105)
Abstract:
This seminar targets compact model development for organic thin film transistors (OTFTs), analyzing some of their features. The physics of the operation of OTFT is reviewed. Assuming on variable range hopping transport between localized states, we show how to derive a mobility expression which depends explicitly on both the characteristic temperature and density of states of the distribution of localized states. Temperature dependences are also taken into account. The effects of the contacts are also discussed. Modeling approaches for capacitances, including frequency dispersion, are presented. A unified parameter extraction method is also described in detail. Very good agreement is observed with experimental data from OTFTs of different organic and polymeric materials.
Biography:
Benjamí Iñiguez obtained the Ph D. in Physicsfrom the Universitat de les Illes Balears in 1996. His Doctoral Thesis targeted the analytical modeling of small-geometry MOSFETs. He worked as a postdoctoral researcher at the Rensselaer Polytechnic Institute (Troy, NY), and at the Université catholique de Louvain (Louvain-la-Neuve, Belgium), where he was a Marie Curie Grant Holder during 24 months. In 2001 he joined, as a Titular Professor in the Department of Electronic, Electrical and Automatic Controlat at the Universitat Rovira i Virgili (URV, Tarragona), where he was promoted to Full Professor in 2010. In 2004 he obtained the Distinction from the Generalit at de Catalunya for the Promotion of University Research, in the category of Young Researchers. In 2009 he received the ICREA Academia 2008 Award. He has coordinated one EU-funded project targeting the compact modeling of high performance electron devices, and he is currently coordinating a new EU-funded project focused on the compact modeling of organic and oxide TFTs. He has published more than 100 papers in international journals.
