An interesting paper in the last issue (91) of Applied Physics Letters from Ling Li, Gregor Meller, and Hans Kosina.
As they say: "The diffusion-controlled injection process in OLED is investigated and the concept of critical distance is proposed. A compact injection model applicable to OLED is formulated. This model is shown to fit the experimental data well and to explain the dependency of the injection current on the barrier height, the temperature, and the electric field. It was found that the field-dependent mobility plays an important role in the injection model at higher electric field."

A paper on FinFET circuits
In this month's issue of the IEEE Trans. on CAD, there is a very interesting paper from K.Roy et al, who present some interesting techniques to deal with FinFETs to create circuits. Have a look here. The model they present to estimate the current is an alpha-law one, but I should think the idea is nice and could be developed further using more complex (I mean, exact...) models.

MIXDES'08
Let me draw Your attention to the annual International Conference Mixed Design of Integrated Circuits and Systems (http://www.mixdes.org/), which has been organized in Poland since 1994 by the Department of Microelectronics and Computer Science, Technical University of Łódź, Poland. For the last 8 years, special sessions on Compact Modeling have been organized as an event accompanying MIXDES conferences. They have become a well recognized forum of CM knowledge exchange. Since their beginning Wladek Grabinski has been their chairman and main organizer. This year, he is being assisted by Daniel Tomaszewski in the session organization.
The next edition of the MIXDES and of the special session on Compact Modeling will be held in Poznań, 19-21 June 2008. You are kindly invited to take part in this event which, I am sure, will enrich you with many satisfying experiences, including, why not, visiting the beautiful old quarter of Poznán, with the cathedral and the old market.

ITC'08
The 4th International TFT Conference (ITC'08) will take place in Chungwoonkwan, Kyung Hee University, in Seoul, Korea, on January 24-25 2008.
ITC is an annual conference which addresses all topics related to Thin Film Transistors (TFTs), from process to circuits, also including simulation and compact modeling.
Abstracts should be submitted not later than October 30 for evaluation.
A number of talks will be given by prestigeous invited speakers, such as P. Miglorato, G. Fortunato, E. Fortunato, T. Someya, H. Matsumura, Y. Uraoka, or Y. Kuo.
No doubt ITC 2008 will be a very interesting conference. Last year it was held in Rome and it was quite successful. Besides, a number of papers presented in ITC'07 were selected to be published in a Special Issue of Solid-State Electronics.

First International Symposium on Flexible Electronics (ISFE)
The First International Symposium on Flexible Electronics (ISFE) will be held in from 6-9 April 2008 in Tarragona (Catalonia, Spain). This conference will provide an opportunity to present and discuss recent advances in all topics related to flexible electronics, from the material to the circuit and system levels. The enormous increase of the applications of Flexible Electronics makes it necessary to create such a conference. The scientific program consists of invited and contributed presentations as well as one poster session.
I will be the Chairman of the ISFE Symposium. Prestigeous researchers from academia and industry are members of the Organizing and Technical Committees: Prof. Michael S. Shur, Prof. Jamal Deen, Prof. Magali Estrada, Prof. Yue Kuo, Prof. Bill Eccleston, Prof. Takao Someya, Dr. Paul Heremans, Dr. Gerwin Gelinck, Dr. Hagen Klauk, Dr. Warren Jackson (HP), Dr. Euan Smith (CDT), Dr. Erik van Veenendal (Polymer Vision), Dr. Tolos Voutsas (Sharp Labs of America),...
Papers are solicited on the following topics:
Materials for Flexible Electronics, Processing for Flexible Electronics, Device technologies, Physics and Characterization of TFTs on flexible substrates, Amorphous and polycristalline TFT, Transparent TFT, Organic and polymer TFT, OLED physics and characterization, Numerical and compact modeling of TFTs and OLEDs, TFT circuits on flexible substrates, Flexible AM-LCDs, Flexible AM-OLEDs, Flexible PVDs, Flexible large-area sensors and actuators...
The deadline for abstract submission will be December 3 2007.
ISFE is organized by the Engineering Conferences International Foundation, together with the Universitat Rovira i Virgili (the university of Tarragona, to which the Chairman, that is, myself, belongs).
The conference will be held in the Hotel Imperial Tarraco, close to the historical centre of the city of Tarragona, in Catalonia (Spain). The hotel, with a high standard of comfort and select international cuisine, is overlooking the "Balcony on the Mediterranean", which offers a wonderful view over Miracle Beach on the Mediterranean sea.
Tarragona is located in the south of Catalonia, in the northeast corner of the Iberian Peninsula.
Tarraco (the Roman name for Tarragona) was one of the most important cities in the Roman Empire. On 30 November 2000, the UNESCO committee officially declared the Roman archaeological complex of Tàrraco a World Heritage Site. This recognition is intended to help ensure the conservation of the monuments, as well as to introduce them to the broader international public.
Speaking about Tarraco’s climate, the famous Roman poet Virgil wrote: "The climate blends and confuses the seasons singularly, so that all the year seems an eternal spring." Thanks to its temperate climate, with an average yearly temperature of 23ºC, its clean beaches with fine and gloden sand, and its singular artistic and architectural heritage, Tarragona is one of the most important tourism hubs in Europe.
I truly encourage researchers on flexible electronics to submit abstracts to ISFE, and have good chances to get to know the most recent developments in the field, to make useful networking and also to enyoy some days in the beautiful city of Tarragona!
