A Compact Model for OLEDs

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."

Abstract

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.
